COINCIDENT FRANKENSTEIN 300B STEREO

Just purchased one of these beasts from Israel of Coincident (quite the gentleman).

I already have a few SET amps that buck the trend of little bass and dynamics that often get associated with S.E.T. amps.

The Frankie is a top notch power amplifier.  Not a good value.  Not a giant killer.  A true, top quality power amplifier period.

I swapped out the stock tubes and what happened next shocked me.  Of course the midrange is gorgeous,  But I did not expect the highs to sparkle and the bass to have definition, texture, and punch.  Sorry,  I intended to say PUNCH.

As always, speaker matching is a key and a stable 6 Ohm speaker will sound best - but these babies are the real deal.

BTW, they retail at around $2,500.

Disclaimer - I am not a Coincident dealer and have no affiliation with Coincident.  I am a NOS tube dealer.

I think you can’t compare stereo and mono Frankensteins. The maximal power is not the only important thing. Is even much more important that stereo and mono have different driver tubes and power supplies.

I don’t have Frankenstein amplifier but I have my DIY 300B amplifier that I did dozens changes and tweaks. I can say, for example, changing powers supply capacitors value, type or model can make more impact on sound than changing of output transformers. Or increasing current of driver tube can change sound dramatically. The amplifier with weaker driver, smaller and sheared between two channels power supply can’t sound similar to monoblocs.

Hi @mclinnguy 

Which speakers do you use with this amplifier?
