How do the transformers sound?
How do you separate the sound created by a transformer from the sound created by tubes, capacitors, other components and different operating point (of the tubes) etc. ?
Osscar : Any bandwidth measurements?

Hi,Only INDEL technical information could have been more detailed (weight, size etc)
Indel datasheets:

I found 2 of these in my parts bin that I forgot about:
Output transformer OTR-40W-2 | GES-ELECTRONICS
It's 4k primary for 2x EL34 in UL.
Thinking about doing an all-eastern bloc amplifier with it with Russian 6P3S-E, 6N6P, russian PIO caps, russian resistors etc and this Czech output transformer.

Sorry if it is a bit OT but can you suggest good European sources for 5U4 tubes and for a power transformer for a EH84 amp? I'm already a TME customer, but I didn't find a transformer with dual 300Vac output with 120mA minimum. Any other suggestions for a EH84 power supply?
Thanks!

Thanks!

I use these: Transformatoren - Voedingstrafo Buizenapparatuur - EOO - ElectronicaOnderdelenOnline
Dunno if they ship international.
Also check out: https://www.tube-town.net/ttstore/, they have 5U4's

Hi mace1337, thanks for your help! I've contacted eoo-bv.nl, they ship internationally, but the shipping cost is almost the same of the transformer, 49.50 for the transformer and 35.00 for the shipping :-(
In the meantime I noticed that for the EH84 Version 2, the rectifier tube changed from the 5U4 to the 5R4, any suggestion about where to get it? I didn't find it in the https://www.tube-town.net/ttstore/, Lo Spaccio di Nova: l'elettronica fai da te nel cuore di Milano, Musikerkram.de, ...
Best regards
