Philco "Super" 19
#16

This evening I started making some dog-bone resisters for the "super 19". While working, I had the super tuned to WSM 650. I had a strong signal, it was coming in loud and clear. After a few minutes, the radio developed a crackling/ frying sound. Using an insulated alignment tool, I started poking around. When I touched the bias resistor, the radio stopped playing. When I pushed on terminal on the end opposite the grounded end, I could see a tiny arc where the terminal wraps around the resistor. I replaced the resistor with one from a parts chassis. Now she is playing beautifully again. There are still a few things I need to do. Beside the dog-bone resistors, Need to install the mounting brackets for two of the tube shields. Right now the 75 is the only tube with a shield. I will be installing the "Super 19" in a reproduction cabinet that I finished about a month ago.

If you ever run into a stubborn, uncooperative Philco 19, 71, 89 or 91  that the oscillator refuses to work, Ron's "super"  mod IS the solution! Icon_thumbup Icon_thumbup Icon_thumbup Icon_thumbup

I recently did the mod changing the 36 tube to the 77 tube with great success. Originally I had this 19 oscillating pretty well across the band with the original 36 tube. But over time it started dropping out below 1100 kHz or so.

So I made the 77 tube modification, and it works real well now.

That Philco chassis is like an armored tank. I had a heck if a time drilling holes and centering the replacement socket.

I'll be interested in how your adventure with the 6A7 mod works out Steve.

I have had a few projects going so, it has been a while since I have worked on the "Super 19".

I made a few reproduction dogbone resistors and replaced the film resistors that I had installed during the restoration.

I had made a reproduction cabinet for the "Super 19" last winter before I started the modification .

Chassis and speaker installed in new cabinet. I used a permanent magnet speaker because I have more chassis than I have original Philco speakers. My thought was since the chassis has been modified and cabinet is a reproduction, I would rather save my original speakers for other projects.

Speechless.
Magnificent job, Steve.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

Man I sure do like your cabinet work!

Hey...

I recently traded my nice Philco 19B, and then acquired another 19B from Kirk.

So...

This new acquisition will become a Super 19 as well! Icon_thumbup

When I start the work (and it will be awhile), I will start a new thread on it...
