Good morning Dwight, My last message to you concerning my trip to the observatory was dated April 23. I didn’t receive any contact information from you and have returned after nearly a week. I’ll

Here is my number, 804 539 1226 Safe travels. Dwight

First I want to thank everyone for their suggestions and guidance regarding my question about lubricating the VFO assembly of a SR-150.? I appreciate the good information. I purchased a new old stock

Hi Richard, I restored a S-40B a couple of years ago.? The advice provided already is of course very sound.? A tactic I like to do is replace the bulk power supply caps first and then fire up the

Will do. Thanks

Dennis, looks like about $9 and change to 06880. send chk for $10 and I will send. Bob w8exv (I'm good on QTH, QRZ)

I would like the dials Dennis WA2DFJ

Justin, I have both dials that are flat. if you know of anyone that needs them they are available for the cost of shipping. Bob w8exv

I want to thank every one for their thoughts!? After a lot of thinking on this, I have decided to let the pot as it is!? Might not be the best decision, but my wife wants the dining room table

I used as thick aluminum I had on hand as it was flat and I figured it would suck the heat out rapidly.? I imagine plate glass would work just as well. 73, -- Justin B. KI5GKD

I wonder if two glass plates would do the same .... ?? I flattened out a warped CD one time this way.....heated some tap water slightly (to about 110 degrees) soaked the CD for a few minutes, and

For folks that have ran into warped dial discs I found a solution, for mine anyway.? I had a Heathkit VF-1 with a very warped disc.? I took it out and applying heat to it and then placing between a

Thanks Paul.? That screw driver wipe technique is something I will need to remember.? I also do a fair amount of old stereo restoration and your technique will sure come in useful. 73 Don N9OO

Jim - I re=capped a Zenith Transoceanic model 8G005 from the 1940s.? There were a couple paper caps I could not get to without disassembling a bunch of stuff and figured the risk was not worth it.?

hello group My Scott slrm dry weight is 90 lbs . At my age, 83 its too much to handle with out help. Its ac/dc so has a hot chassis and i use an isolation transformer for my safety. barry

The worst example of high impedance rivets that I have seen was in a Gonset G-63 receiver.? I could not successfully align it once the caps were replaced until all of the tube socket ground rings

We sometimes forget that a chassis is often a high-current AC conductor, sometimes carrying several amps of tube heater current. To Don's comment, bonding to a single common chassis point often

Don, John, does the “common ground return” mean any old connection to a “ground wire” scheme, or is it a specifically designed wiring scheme ? Sent: Sunday, May 4, 2025 8:26 AM To:

Hey John,? That's a very common practice in audio gear, naturally, to avoid ground loops. 73 Don N9OO

Yes!? I have even wondered if soldering socket ground terminals to the chassis is enough to ensure good performance.? Solder is not the perfect conductor, and does not have the best strength or
