Coincident Dynamo 34SE integrated tube amplifier used less than 100 hours. It was purchased last year in September. It is in mint condition. I wanted to give a SET amplifier a try, but this amp just didn't have enough power for me. This amp has the power supply caps and input caps upgrades to double the voltage as in the MK. II to provide bullet proof reliability and superior performance. Comes with upgraded tubes: 2x JJ EL34 tubes, 2x Adzam 6SL7 tubes - cryogenically treated, platinum grade and 1x Gold Lion 5AR4. The amp is only for sale within the Continental US.
