Electrolytic Capacitor Replacement?

[jhalphen]

Hi to all,
Hi Ruru,

Thanks! for the photos of the tube labels & entire chassis.
While waiting for Ron-L's possibly exact chassis data, i did some analysis.
- your chassis CT1905 has a Pwr Xformer, the CT2303 doesn't.
- yours: E series 6.3V parallel heaters, the other, series string (no Pwr Tx).

V oscillator and Output in yours is one tube, 6EM7, the other 13EM7
same tube ? different filament supply.

I've highlighted in red the V oscillator and V power amp sections (all in the same tube). Could yield some info such as tube pin voltages (& waveforms if you decide to try your Scope).

6EM7 tube data here, on our french site : shows pin functions & typical voltages in circuit (here V oscillator & output Amp).

Tube pin IDs in last photo. Seen from UNDER, as always in tube data books

This is just analysis work in case Ron-L doesn't have the correct schematic.

your have to go to the first post you created & edit it's main headline (should work!).
