Truetone D-2026 Good Phono But Bad FM And AM
I got this radio a few days ago and went through it cleaned it completely
out, resoldered several connections that looked bad, replaced power cord and speaker. The phono input works great and i have crystal clear sound almost, but on am all i get is a little static and poping, and on fm i hear no static at all it will pick up one fm station but no where near the correct volume. i assume its probably a bad resistors and or capacitors? could this be a faulty tube? they all glow. does anybody have a schematic for this set? several of the caps and resistors have worn markings and the backplate only lists the tubes and transformers. There is also a transformer right before the speaker (two output wires from amp to one side and the other two go directly to the speaker, this is not a speaker that requires a field connection also either so its on the audio side) this doesnt even appear to be original bc it was just set in there where the orig was supposed to be and the wires are taped, is this necessary? i know newer devices do not have these? is there a generic replacement? |
