In a recent Shure fatboy rebuild from 1941 and 1943 the re-plating of the zinc frames were called for, but it was up to me first to get rid of years of nicotine build-up from chain-smoking radio

That type of thing happens when you inadvertently mix an ammonia based cleaner with a chlorine based cleaner.You get the same kind of gas that was used on? troops during WW 1.? Ain't good.? Even

This is an important caution below from Kim. I did mix cleaners together for a difficult cleaning. It hurt my lungs and put me in bed for a day. I did recover. I realized I was being poisoned before

Just a caution here.? Be VERY careful about what you mix together.? It's very easy to poison yourself from a BAD reaction of the chemicals.? Just a heads up for others.? Personally I've always

Latest photo of the chassis as I am removing and cleaning each individual assembly. Just took the top bread slicer out and I have a seperate plastic container I will fill with the Fan-monia and let it

Mcmaster carrs prices are absurd....and are? per foot !! I used rolls of belden 10 kv test prod wire.? It comes in red or black.? 18 ga stranded...and silicone rubber...and flexible as spaghetti.?

Good quality coax. With SHV connectors.

Akek, That worked! Thanx. My Kenwood has a soft start in it already (Kessler). My Henry (2K-3) about once every three months will trip the breaker when turned on. I can live with that I guess. The amp

Hi Bob Search for 100A 4000W High-Power Soft Start Circuit Power Board for Class A Amplifier Amp 73, Alek.

In the soft start device I'm talking about, it gets switched out of circuit by the 100A relay, just like the resistor in a normal slow start. Alek VK6APK

The SB220 has a separate filament transfomer but since the line feeding it and the plate transformer is the same, any sag on the line voltage due to plate primary current drawn by the plate

I have mixed emotions about NTC resistors.? I tried one on my SB-220 and found that the resistance would change between idle and full plate current.? The large current change caused the filament

Alek, Angus, I couldn't make those ebay numbers work but if you do a search on ebay for "NTC resistor" you get several. I had to use one in my 50 amp Astron (RS-50) linear power supply. It would

G'day Angus. Sorry for the delay. I missed your email and I'm just cleaning up my emails and noticed this one. Yes, the NTC works. I use them in this form for a lot of amps that I build. See Ebay Item

I’ll take a look at this, thanks a bunch.

SHV connector is ....'safe high voltage'.? It's basically a reverse gender BNC connector.? ?Typ rated for 5 kv @ 2 amps. A HN connector is a ...'high powered N connector'.
