dear all
I am the owner of an old DIY valve power amplifier bought a long time ago, so i decided to investigate on it
First of all I saw it fits a couple of tamura XE 45 8 out transformers
I read tamura sheets seems that the out trafos are not suggested for a 300B PP
What's your opinion?
First Stage 6SN7WGTA (PHILIPS) Driver 6SN7GTB (SILVANIA) power tubes 300b super 4300a golden dragon, rectifier CV 378
power inductor Tamura A 4004 power trafo Tango 10422
your impression is highly appreciated

Welcome!
The OPT has an 8k primary, so it is quite ok for a 300B PP.
I do not have specific knowledge about these transformers, but generally japanese iron is very well regarded, so I think you have good stuff there.
The 6SN7 can be configured in a myriad different circuits as driver, so only naming the type and brand does not help us much.
Is it currently operational? Can you post some pictures so we can have a look at the DIY skills of the builder?
best regards,
Erik

unfortunately I am not an expert so I cannot comment which kind of circuit it is
maybe someone can help me to understand

Send it to me.
I will test it, and Post the results.
Then I will listen to it, and post my impressions.
Then I will purchase it from you.
Sorry, I am Just Kidding (except I might purchase it from you).
Please, tell us what loudspeakers you are using, and please tell us how good your amplifier sounds on them.
Enjoy, you have a fine amplifier.

you are too much far from Italy.....
but i do not want to sell it!
I am looking for one guy who can help me to understand the technical caracter of the amp (how the amp has been built, which topology was applied
unfortunately I don't have the amplifier's electric scheme
forgive me I am not fluent in english but I hope you can understand what I mean
