Hi all

I have an old STS-770ES tuner with some problem with the memory preset stores i have change the 0.1F in the reset circuit, but still the time it can be without power is very limited. I belive that the other parallel cap is leaking dut to the aging and it have always been hot due to the placement on top of the hot amp TAF-770ES.

I will like to have the TA-SA5ES tuner service manual to if it is the same way it's build. i have just come accross this tuner but not yet got from the old owner.

kind regards
