If it does turn out to be a blown attenuator, perhaps the best option is to use an HP attenuator instead (they are much more available). A small bit of logic is needed to remap control signals and

I've done this for many, many years, and usually my reason is I cannot fit a higher wattage resistor in the same space as two smaller resistors sitting upright like this. So, I would guess that a

Thanks everyone; thankfully mine is a later production version, post B020319, so hopefully not the unrelaible version. I've checked the 100MHz reference and have healthy outputs on all 3 reference

Unfortunately, there are no parts, except from another Tek attenuator. Is it blown, or are the contacts "dirty"? These were often damaged by DC or excessive input power. If it is damaged, you need to

I do not have the factory tool, but I have a set of snap ring pliers that have round tips that work pretty well. I use masking tape over the outside of the vernier ring to prevent inadvertent damage

Hi Jeff, I've been with Paypal for over 20 years. They have security measures in place like every other bank. I've never had an issue with paying or receiving money from anyone either. I won't use any

Ah! Great! I have a pair of snap-ring pliers that kind of work. I gave it a bit of a tug, but didn't want to get aggressive with it not knowing that I was yanking on the right part or not. I have the

To get a high-wattage resistance, there are a couple of options: Get a bigger resistor; or make it out of a series or parallel combination of lower power resistors. Tek chose a series combination, and

There is a nut inside the fixed part of the counter dial. It takes a 2-pin spanner wrench made by Kilo, or you can make one, or if you have very strong fingers you can use a round nose plier in the

In my >60 years experience with this type of equipment I have seen these two series resistors (modification?) in many different situations and I agree with Jeff 100%.? He has it right.? ? ?Terry

Anyone know the trick to removing the Delay Time Position Vernier pot? I have the fine adjustment knob off. Now what!? Befuddled.

Today, with that which shall not be named still around? Ummm, FairRadio (in Lima, OH) has (had?) some of the more common ones in back... - (No affiliation, just a customer). IIRC, they were in what I

Chuck Harris wrote: The main reasons that I think Tek did this are 1) that the two resistors appear in the schematic in the service manual, and 2) the resistors look like matches for resistors found

My hope and intent is to write up a 465 tear down page - perhaps on the Tek Wiki? Somewhere where I can create some hierarchy and include inline pictures. Been parallel researching methods. EEVBlog:

Resistors have voltage ratings, and power ratings in addition to their resistance values. It is probably not the voltage rating that is at issue here, but possibly the power rating. More likely,

Thanks. No, I have not taken the vertical out yet. I did think about it but since I can get to those contacts without the hassle, I will attempt it as it is. But would you document the steps you did

Me, too.? I used to order tons of components for work, and the few times they messed up, they made it right immediately.? Could not ask for better customer service!Jim Ford?Sent from my Verizon,

Usually I wait until I have about $100 worth of stuff before I order from Digi-Key or Mouser.? Just so I'm not paying $10 shipping for $20 worth of components.? I don't like Newark because they
