Re: L75 Amp Main Power Switch Availability
Wow Steve! I bet this is really common... to find this kind of failures on old equipment as you said. Now I won't be surprised again. Never happened to me before with Collins but sure that doesn't mean anything. I am sure they were also plagued with problems too. Just take a look at all the Service Bulletins they published fixing lots of problems.
With Heathkit you expect surprises (like completely missing solder wiring up to wrong wiring) but never have had that experience because from day one I remove all components and start assembling again, using the manual and modern resistors/caps, etc. and I have had terrible failures of my own but was able to discover them on time. But this is the second time it happens to me with Drake.
Had another cold solder in my restored Drake TR-4C... a very small cap was not soldered at all in the center of one multiple connection points and was behaving erratic. One of those kind of failures that by giving a thump on the chassis will fix it. Any way, spent one hour just to finally find where the fault was and fixed it. This radio was in use here in YS for many many years. Too bad the SK YS colleague who once owned it was no longer available, to ask him if he had any troubles with it.
There is so much wisdom in this list guys!
Thanks for all what you share with us here.

Anyone know the dimensions and thread size(s) needed for that ceramic standoff. I have some that look like they might be close and would be happy to pass one along if it will fit.

Nice to see my efforts are remembered!? Peter has described the
fix precisely (probably better than I could!).? It was a good
repair in that it left the tuner with switch contacts that
appeared to me to be twice the amperage as original and of course
transparent repair when completed.? The only "special" part was
making the shaft coupling which had a radial offset in the fixing
screws to accommodate the flats on the shafts not aligning.? I
have pictures of start to finish somewhere if they can't be
found.? I think the biggest cause of failure of the switch in the
Drake and other tuners is operating into the wrong or no load then
switching hot to correct that.

It copuld have been lightning, but also a severe mismatch or antenna system fault at high power can cause some crazy nasty voltages and currents. 73 -Jim NU0C On Fri, 2 Apr 2021 16:37:10 -0700 "Patrick P" <sbus1313@...> wrote: So what smokes these things anyway?

Not sure....hot switching perhaps?
I have to wonder if those contacts are a little under rated given
what could go through them, especially in a high SWR situation, even
though they are doubled up.? Lightning....yup maybe.? That could
easily be right in the line of fire!

Looks to me that 1 of two things may have happened.? (And have seen both things, just not on a 2000)? 1.?

I drove myself to the North Lawrence fired department where they took me to the hospital.
One stint inserted, but the rest of the plumbing seems to be okay.
More doctors to see, and I have enough pills to start my own drug store now

date.? I do add a tag on the back of the radio if a piece comes into
the shop for a repair, alignment, LED bulbs added, a mod done, etc.,
that documents what was done and what options are inside, if any.? I
have been pretty consistent with that project, at least on the major
items. Trying to assess worth is also not easy as it is variable,
and is highly dependent on your available buyer market.? Used gear,
especially older used gear, doesn't have a lot of potential buyers
in this area, so trying to dispose of gear can be really tough.? I
have to drive 6 hours now to get to the closest worthwhile ham
fleamarket, so you are pretty well restricted to? a couple of those
a year or selling online.? The latter involves shipping, which can
be near impossible for radio gear weighing 75 to near 200#.
Every time I hear the words "I'll sell it ALL to the 1st guy with $5
grand", it makes me cringe!? Time to start getting busy!? Let's hope
this pandemic is over by next fall so we can attend some of the
fleamarkets, though it's not looking particularly good at the
moment.

I’ve been lurching into the creation of a spreadsheet so that
my XYL has something to start with if I suddenly depart. I do
need to include tools.?
I’ve sold about 70% of my coins already. Collections are fun
in the acquisition, then sit in a safe. I’ve decided to cash
them out, keeping a few favourites.?
This post does remind me that I need to finish that.?

with appearance per my requirements, but chock full of 813's,
4-400's,
big heavy Hammond HV xformers, roller inductors, and big caps.?
There
was a box of new 4-400's and another full of 813's. Three
working
rotators including a Tailtwister.? He told me that if I didn't
take it,
he would take it to the dump that day.? He's in a suddenly

situation with the health of his wife, his own health, and his

tools,
including power tools, most of which will be for the new owner
to sort
out what stays and what goes.
Now I have to figure out what to do with them.? But I just
couldn't let
them go to the landfill.
I still have to rescue an HF GEM quad with enough spare
spreaders and
spiders to make 2 more, an MA-40 crank-up, which is now on the
ground,
and a TA-33 triband beam.
Plan now - I know I am, though it will be a bigger job than it
was!

I am a "Life" member.? I do not want to burden my XYL any further when its time to deal with my stuff.? I have personally met the folks at HamEstate (Orlando Hamcation 2018) and can personally vouch for them.
?
I have put their contact sheet of paper in with the other important estate papers in the safe.? I am just carrying on in my interests with a clear mind.
?
I have no personal interest in them, just a satisfied customer (or should I say my xyl will be a future satisfied customer)
?

I am also sometimes worried about that subject.
No one at home follows my steps and, in YS, we have no hams. All are dying, and we are no more than 6 hardcore ones who still do DX. The rest only work VHF repeaters and Sats.
I am very small here, compared to you guys (everything fits in a small 1.8 x 2 meters room) and I am worried at 56.... now you, in North America, have accumulated tons and tons of equipment... Have to act As soon as possible and keep only the essential... I guess. Cause it’s going to be a problem for your XYL who will just sell everything by metal weight or simply take it to the dump.
