Coincident Technology Dynamo 34SE MKIII

@tswisla It doesn't use 300b tubes.  I think you have it confused with another amp.

@smrex13 I have it right in front of me!  See their website!!!

The Dynamo MKIII is now available on special order optimized for 300B output tubes instead of the EL 34 which is still standard.

You are both right.  The amp can be special ordered with 300B output tubes.

@tswisla  Wow, didn't know they had the special option!  I stand corrected.

Yes I was considering the 300B version but opted for the EL34.I sold my MKII with the stock tubes keeping my vintage tube complement.Tube rectifier is a 1945 RCA 5AR4GY with hanging filament,power tubes are Genalex KT77's,and signal tubes are Tungsol JAN 6SL7WGT.I have spent hours auditioning several brands of vintage and current production tubes with my MKII and in my opinion for this amp the aforementioned tube complement is the most desirable.Power cable is the Silver Ghost by Mark Tunis and interconnects are Mad Scientist.Will update on my impressions after 100 hours.
