A standard procedure with the TR-7 is to remove each PC board, sparingly apply DeOxit to the edge connectors, and then re-install the boards.? Using DeOxit on the switches and potentiometers is standard too. BUT remember, ONLY a little is needed.? And don't forget the Jones connectors on the rear.? Then, if problems remain, they can be addressed.? But clean connectors is a must before any other tests are typically done.? Please keep us informed...

Hello, I am new to the list and I am having a PTO problem on a "new to me" TR7.? Please excuse me if this has been covered before. I done a very cursory check in the archives without much success,? My problem is two fold.? First the TR7 jumps freq both during RX and Tx by a +200 hz approx.? I have done the usual adjustments re 10 v reg, passband tuning etc.? The second problem is mechanical. The digital readout and the mechanical dial do not agree. The usual attempts at adjustment from the front panel are not successfull. There is not enough "correction range". BTW I do know the digital reading is correct.? It seems as though one of the dial drive gears may have jumped a tooth. I can not find a drawing in the maint manual that I have.? I do not want to get too involved until I have a little more information.? Can someone on this list refer me to a site where this may be covered?? Thanks in advance.? 7 3? Lorne?
