My TFM 25 has a bad input board (I think).

Looking for a TFM unit with the same RCA input board. If you have a junk unit or this piece alone, I would appreciate it.

The left channel is completely distorted, right channel is fine. Goes into protect if you turn it past 10%.

What's odd is if I swap the leads on the input board, the problem follows the channel of the board. I tested both sides of the amp and both channels work free and clear with the right channel of the input board.

I really don't want to spend $300+ to have it repaired when I know its something simple.

    The TFM-25 was notorious for bad solder joints. especially around the transistors due to heat build up. Look the boards over closely.

    I had the entire input board desoldered and resoldered, with new transistors too! I don't know what gives :(
