Re: Who made these HV cap kits for the PS2000?
Dave That is true, today's vendors publish this data but if it was indeed important to the design, hallicrafters would have added this data to the parts list.? The only description I find in a hallicrafters parts list is a hallicrafters part number, not the component manufacturers P/N.??
What is the price difference in filter capacitors between a 5 ohm ESR and a sub 1 ohm ESR???
Lets do a back of the envelope calculation on how much power is dissipated in a 5 ohm ESR filter capacitor.? Once fully charged, the voltage across it will fall between the times when the the rectifier is not forward biased.? If B+ current is 100mA and it takes one millisecond to recharge the filter capacitor to full peak voltage and that charging current is one amp then the peak power dissipated in the filter is 5 watts.??
Average this 5 watts over one cycle of the AC line and you get 5 watts X 0.06 or about 0.3 watts average.? Considering the surface area of the typical filter capacitor, do you think that you will notice the temperature rise caused by 0.3 watts? Regards, Jim

Hi,
I have been taught that the lowest ESR is the best value. Never questioned that guidance.? I suppose you could call Hayseed and ask them about the ESR value of their caps.

Re: Who made these HV cap kits for the PS2000?
The esr for the original caps came from vintage catalog search of what was printed on the original caps. That was probably 10 to 15 years ago. I went to the site and found that they do not quote esr ratings on that line of caps now. ???
The C-EC50-50-500CE I bought back then had wire leads. So, everything has changed.

FOOD FOR THOUGHT. The original capacitors are 90uf/500v with an ESR of 1.5 ¦¸. I found dual 50uf/500v capacitors with an ESR of 0.15¦¸ at a lower price than the 90/500 caps. Paralleling the dual caps yields 100uf at an ESR of 0.075¦¸.

ESR is relatively high for electrolytic caps and low for paper. It is

Leakage is again comparatively high for electrolytic caps and should be
vanishingly small for other types.
Heating of electrolytic caps can come from either source.
Electrolytics absorb some power to maintain the electrolytic dielectric
which shows up as leakage.

Hi,
I have been taught that the lowest ESR is the best value. Never questioned that guidance.? I suppose you could call Hayseed and ask them about the ESR value of their caps.

Re: Who made these HV cap kits for the PS2000?
Unless you are working on a SPS, the ESR of a new cap from a
reliable source (that means Digikey, etc, and not ebay), as it
applies to use in a old tube rig, will be absolutely
satisfactory.? And the temp range, again in the tube rig context,
is more about other components heating up the cap, rather than
their internally generated heating as a result of the ongoing
reformation process and the associated leakage.

Re: Who made these HV cap kits for the PS2000?
The original caps had and ESR of 1.5 ohms. You might try asking Hayseed what the ESR of their replacement is.
From http://www.tubesandmore.com/ C-EC50-50-500CE CAPACITOR, ELECTROLYTIC, 50/50 ?F @ 500 VDC.
FOOD FOR THOUGHT. The original capacitors are 90uf/500v with an ESR of 1.5 ¦¸. I found dual 50uf/500v capacitors with an ESR of 0.15¦¸ at a lower price than the 90/500 caps. Paralleling the dual caps yields 100uf at an ESR of 0.075¦¸.

I played around with this radio a bit today and have a couple of questions.? I injected a 25.1 MHz signal into the VFO input and was able to get about about 6 watts on modulation peaks and I was able to "hear" myself on my NC-183 receiver so the transmitter is at least sorta working.? With my 20M Inverted Vee attached I hear no background "hiss" and the receiver sounds pretty much deaf.? I can hook my signal generator up directly to the antenna connector and tune in a weak signal on the SR-46 but with a direct connection it seems like it should be way louder.? I tested all of the tubes and a few were marginal but I don't think they should cause it to be deaf.
This was advertised as tested/working so I need to verify this lack of background noise doesn't sound right before I start dealing with the seller.? I know next to nothing about 6m so maybe a quiet background is normal, but I don't know.

Here is a ham owned cap company that has been around for a long time and produces some of the best cap kits for our hobby.? ?t As well some of the best ESR values for electrolytics?used in our boat anchor power supplies. For those of you not familiar with the term ESR. Here is a brief definition: Equivalent series resistance?(ESR), also known as internal resistance, is a value representing the loss of useful energy in a simple electronic circuit consisting of a resistor and an ideal (perfect) capacitor. Technically speaking, the energy is not lost but is usually dissipated as undesirable heat. For those curious about this spec there is plenty of good reading on the?internet.?

Looks a nice job.
I printed these in abs for my ps2000 . They use the capacitors suggested by Walt in his repair manual.? Ian

Re: Sx100 question on 50.5 kc alignment
Thank you so much Dan. Yes I am figuring out that the audio generator is my weak link. It is just a hobbyist tool and not geared for the 50kc area needed to align these IFs. I am looking at something more suitable for this task. That certain auction site has many of them. Especially Leader and HP versions. This is probably where I need to be focusing. If I am going to continue doing projects like this, it is clear the tools need to be up to the task. I will keep the posting as it moves along. There will be questions for sure and I appreciate those willing to share knowledge. I am seeing HP 651s and similar that would not break the bank but also thinking long term. Am I just buying something to get by or something that wont need a lot of work to make usable. Will dwell on it over the weekend and see what comes across the searches. I see some Amazon versions that are imports but just how good of job they would do leave some doubt in my mind.

Re: Sx100 question on 50.5 kc alignment
? Hi, Keith. You¡¯re going to find it easier and more effective using a VTVM for peaking and nulling during most stages of alignment. Moving a DC flat line up or down on the graticle of a scope is just less precise and more tenuous than watching a pointer on a meter moving up or down.
And don¡¯t over focus on the manual¡¯s mention of ¡°approximately 1 volt.¡± That¡¯s not really the goal itself. The goal is to peak each can when using a minimal input signal and that is ¡°around¡± a volt or two to begin with. Actually, anywhere from 1 to 3, 4,, even 5 volts could be OK, though lower is better. Point is, you don¡¯t want to force a massive signal into a circuit and align on that. Lower, less, minimal is almost always better as a signal source and will give you a better real world alignment in the end.
As you proceed with peaking T3, 4, 5, and 6 you may see peaks in each case and your 1-2 VDC to start with may increase so much you will want to reduce your sig gen signal strength to get back down to around 1-2 volts before making a second pass through the four cans.
I suggest your best bet is to stick with a VTVM and focus instead on optimizing the sig gen you have in getting a reliable and accurate 50.5 kHz out and being able to regulate the output for ¡°around¡± 1 volt in the VTVM. Don¡¯t obsess over 1.0 volt. Get it as near that as you can. Most alignments are a matter of higher or lower or better or worse and not so much fixed absolute values.
You current signal/audio generator may be your weak link right now.
Keep us all posted.

?Those that have more experience with testing these points in the SX100 or any other radio that normally uses a VTVM to check DC voltage.....can I do this with my oscilloscope?
My probe is a 1x & 10x. Could I not use it at 1x to measure this voltage coming off test point B in the SX100?
Looking to get around 1 vdc here when tuning the 50.5 IFs.
If I am thinking wrong, please let me know.
Just thinking this would be more stable than my vtvm.

Clark,
What is the offset distance between the two shafts, as precise as you can get. Vertical and horizontal I¡¯m willing to try to machine from some plastic stock gears I have that was from some previous projects that I didn¡¯t use. ?Would make a set of 3 with the plates to hold the idler in place. ?Need to also know the distance between the ends of the two shafts as well. ?Before making I can email you a paper template to make sure we have everything ?correct.?
As a quick fix, the nylon bars drilled to go on the shafts with a grove for the o-ring would be a choice as well. ?If you want to try those can machine those for you as well. ? I have different sizes of nylon and delrin bars available. ?
Always need to keep as many of these great old radios on the air.?
You can contact me direct , good on QRZ

That might work Don.

How about a piece of 1/2 plastic rod, drill a 1/4" hole down the middle, slice off a couple sections and sleeve them on to the two shafts. Then run an O ring as a belt like Heathkit did on the HW 101?
