Well.....I finally got motivated to start on the Allen 20 watt amps I have. I was considering modding the circiut but I've decided to give it ago stock for now. I've completed the recap on one at this time.
All caps were replaced save for one that goes to the extension socket. The carbon comp resistors were replaced with metal film 1% resistors. The red resistors were left for now as they are supposed to have "mojo" to them. Can cap was replaced with a 40uf + 40uf can on top and 10uf underneath.
Fired it up and it was nice and quiet. No red plating and no noise. Listening to 20 minutes or so of music and all is well.
It's been running now for about 40 minutes or so and no issues and it's not hot.
Time to get going on a second so I can hear these guys in stereo
