Thanks for all the helpfull info I've found here. I have a TFM-35 that I have now sent off for repair 3 times. Each time at about a two year interval. I've got some time on my hands right now, and a rudementary knowledge of electronics (have designed and built DYI projects such as active crossovers and power supplies), and I'm wondering if there is any basic manual or thread covering how to get started tracing problems in a faulty amplifier?
I've downloaded the TFM-35 service manual, but unlike every other service manual I've ever had for any other device, there is no trouble shooting flow chart, etc.
Any advice for a newbie?
