Hi,

Any experiences on the music angel's 845 tube power amp ?
It looks nice and not expensive on ebay.

Best regards,
Franck

And don't be surprised when the power tranny goes up in smoke...

(speaking from experience here..

)

just now- looking at his (lampizator's ) schematics- seems that removing R9 is somewhat suspicious move........in that case driver toob will have grid floating.........

anyway - besides seeing it on mentioned site ,I have no any xperience with that amp ;

Mini....other impressions?

I have just seen the web page "lampizator", many thanks for that link. Yes that is what we get for a cheap amp!

I wonder since when that experience hapened and if the quality remain the same nowadays. more experciences on that amp are welcom.

"in that case driver toob will have grid floating". if il float on the right voltage, it coold be a normal DC coupling, then there is no nedd of the capacitor, right ?

and..I do not like it's PSU (voltage doubleur).

Best regrds,

Yes sir, RC coupling or DC coupling, but not in half way.

I have one of these amps 2007 version, can someone explain how these modifications shown, help improve the sound?

I would like to have a go at improving it.

Hi,

arvin, is it possible to post the circuit included with the amp and also check if your amp has been really built with respect to that circuit.

Regards,
Franck
