geloso: G1/1110U (G.1/1110-U);

I am looking for any information on this model, most importantly a substitution for the EL503's.

The schematic would help to find a solution. Maybe Johu can tell us something about the 3 other tubes?

I just post this to bring this up again for Johu who made the effort to upload this new model.

Hello Jehu,
This is a very nice amplifier but with very rare tubes. There is some information on converting to EL36's at http://www.chambonino.com/modify/mod1.html . There are also two EL503's for sale at ebay .They are expensive at GBP 80 each. I have used this supplier before and found them to be reliable..
Kind regards, William

have the complete manual and schematics about Geloso G1/1110A. Tubes: ECC83; ECC83; ECC81; 4 x EL503. But there are no transistors, and therefore different from the model in rm.org.

The model in rm.org is named: Serie II. Maybe my documents are for Serie I ?

Should I add a new model? What is the different between G1/1110A and G1/1110U? The tube list in 1110U is not complete.
