I have just finished recapping my "Hippo" 48-460. The set seems to have too much treble and sounds shrill. Also, the volume control doesn't have to be turned very much for the set to quickly play very loud. I followed the schematic and replaced the capacitors one at a time. Also, I don't remember where it was connected to, but it looks like a previous repair had a .001 400v paper cap in the audio section. It wasn't shown on the schematic or parts layout in Ryders so I clipped out the capacitor. I wished I had made a note of where it was connected.
Would changing the .02 capacitor from the 50L6 plate to floating ground fix the tone issue? After that is completed, the set is going to need realignment as I replaced all caps in the RF and oscillator circuit in the same position the originals were in. The set has high pitch squeal when some stations are tuned in.
Does anyone know where to get a new volume control with the long shaft? The on/off switch is broken. Had to wire around it to test the set. If I can't get a replacement, I might have to just insert a line switch in the ac cord and be done with it.
