toshiba: toshiba Model GP-33F

Hi all,

Can you help me with a weak left channel? Same low volume when I try both speakers on left channel.

Thanks,

Charlie

Hi Charlie

You are referring to the model GP-33F, which has at least another assembly of the push-pull stage.

Please create a new model here in RMorg and ask for the schematic.
-> Edit: No need to create another model, it is here
This thread should be moved.

Moreover, pictures of your model would be appreciated ;-)

If the right channel works you may do comparative measurements at the pins of the final stage transistors. Be careful, the germanium transistors are easily destroyed. Always refer to ground and avoid shorts.
But first try to bridge the output capacitor with a known good one.

Kind regards
Marc
