Hi All, I'm testing my 38-116 after complete replacement of all paper caps, and most of the resistors that were out of tolerance. This thing was a mess as far as the chassis was concerned. It was shipped with chassis in it. Needless to say when I got it 4 of the 5 shafts were snapped off and the back of the chassis was bent up with the input trans. bent too. So I welded 2 of the shafts, made one from scratch and mechanically made the other one work with a butt connector and a few alterations to the bracket.
At any rate it works and works very well. The plate voltage is a little low on the output tubes but it still plays well and loud if wanted. My main question is with such a nice big speaker I would think the bass output would be very noticeable but mine is negligible. The 3 position switch on the power switch does not seem to do anything. I can get a little more lower tone by using the treble and sensitivity pot(which was a lot of fun tearing apart to fix the shaft). But the bass on the power switch does nothing. Is there something I can do different or replace to get some bass. That shaft was broken also but I took it apart and was able to braze it back together and cut in a groove for the C or E clip and it works well except for no bass.
Any suggestions or help would be greatly appreciated!!
