Vtg GE General Electric T-151B Wood Table 8 Tube AM FM Radio Works Needs Service

Vintage General Electric T-151B Table Tube Radio "Musaphonic"
Has phono input, AM, FM, and FM AFC
This radio works and has original knobs. BUT it needs service. Both AM and FM play, but between stations there is a loud hum that comes and goes while on frequency. The audio sounds good, but there is other distortion in the audio. It also has trouble tuning to the right, as if the string inside is slipping.
The indicator light works and lights up behind the indicator, but sometimes doesn't come on right away.
The cabinet is in decent shape, but does have minor chipping and wear. Refinishing would not be too difficult. The speaker grille is in very good condition and wouldn't have to be replaced.
It measures 17 1/2" x 8" x 11 1/2".
