My generator is a PE-75-AF the last of a long line of models. Voltages measurement were taken with a Fluke meter. Have TM11-900A which covers my gen set. Found the TM over on smokstak. The house I

Thanks for help and suggestions. The 6U8 mixer was microphonic (as is common) and replaced with a 6EA8 equivalent improvement. Nice! Now cleaning rotor bearings in Main Tuning capacitor and hoping it

Richard, and anyone else As to the first S-40 speakers being a carry-over from the S-22R.. I found this: The s-20 appears to have an electrodynamic speaker…. with a hum-bucking coil .. and with

Yes it is. I have one as well that used to belong to Gen. LeMay. Good story about it as well. 73 – Mike Mike B. Feher, N4FS 89 Arnold Blvd. Howell NJ 07731 848-245-9115 Sent: Friday, January 13,

In the 1960's, CAP Comms units were issued a large number of PE-75s. They had a Briggs/S engine and would put out 2.5kw 24/7. The manual showed the gen connected to 3 or 4 GI gas cans interconnected

The two best candidates are: 1 a microphonic tube, 2 a microphonic I.F. can. It could be as simple as reseating the tubes. Just about every part and solder connection in the radio can become

I am not specifically fsmiar with the SX-71 but this seems excessive. Certainly mechanical. Could be the oscillator tube? or more likely something loose.? Check the tuning cap and tube by tapping

The SX-71 I am working on is tuned up and operating fine. However, when operating cw, the frequency shifts as much as 400 Hertz if the table is bumped or radio tapped. Even after good warm up and

HI dcc98 and any others RE: “creative wiring in houses……..” interesting, anything was possible in the days of the wild west, some of the next is said in hindsight, after some sleuthing..and

The service bulletin fir the S-40a says that a field coil speaker was used in the first 1000 units. A PM speaker was used in subsequent production.? I compared the part number with the S-20R, they

Over the years have seen some very creative wiring in houses!! To save wire only run a hot wire to a bathroom for lights then hook to a metal water pipe for a neutral to make it work. Older houses

That is right,,, they can match the color not the texture. The "blob" texture of the SR series is a good example and some of the old textured and wrinkle finishes take a little creativity to

listening in with interest. Paint stors can match the color, but what about the matt-gloss characteristics and maybe what works on metal... Matching paint always seems tricky. 73? don VA3DRL

Chris, If all else fails, try Sherwin-Williams paint stores. Clean your panel with soap and water. Then take to S/W, they can scan several spots on the panel and mix an exact match. Walt Cates, WD0GOF

Try here, its in our Database Section, there are a few entries describing the SX-62 paint scheme. /g/HallicraftersRadios/table?id=4841 * K2WH* *Bill's QRZ Biography (

Hello.? I'm new here.? I'm rebuilding a first run SX-62 with all the loctal tubes in the IF chain.? Anyway, I am going to repaint and re-letter the face due to it being scratched up.? Can anyone

I have to look at the schematics but it seems to me the S-40 has an electrodynamic speaker, at least in early versions but the S-40A has a PM speaker with a 1K resistor in place of the field coil. The
