Custom 300b amplifier
« on: 12 Jun 2018, 10:09 pm »




 :popcorn:Just look at this amp. I have owned it for 8 years . 8 Watts of single ended bliss . WBT posts and RCA'S.
Tube filament supply coleman boards . Frequency range of 20hz to 26hz . It has always sounded great .
I have had 6 300b amps , including a Viva . This is the best non- transformer coupled amp I have heard.
I am looking for 2300$ with EML 's and 2000$ with no 300b's
tubes
2=300b
2=5as4
2=6bx7
1=6sn7
can be driven to full power at .7 volts

There is two big output transformers in this amp.

He probably means the input tubes are not transformer coupled.  I have a 45 SET amp with transformer coupled input tubes and I have to admit, it's pretty nice sounding.

It means no interstage transformer aka RC coupled.  The owner switched to an amp with a shebang of transformers in it and thus the confusion  :green: I heard the amp in question and it is excellent - full bodied and spacious sound and the build quality is as good as anything out there.
