Item specifics




I have a pair of Dynaco Mark VI tube monoblocks @ 120 watts each for sale. They have been gone through electronically and all components likely to be affected by age have been replaced.

Thirty plus year old capacitors tend to get iffy, therefore:

Replaced in each amp:


5 x multi-section electrolytic capacitor cans

2 x bias supply capacitors

4 x 220K power supply summing resistors

4 x power supply rectifier diodes

2 X RCA gold plated input jacks


Although they were functional and sounded excellent before this work was done I now fully expect that this rejuvenation has added many years to their life expectancy.


The music they produce is superb and the timbre is that tube sound we all want with no loss of detail. Unlike other Dynacos of their era they have great frequency response and produce thundering base.

Some might ask why do the work and not keep them?  The answer is I was tempted but we are downsizing and I need the space, so the buyer reaps the reward. And buyers - please don't forget they are big and they are heavy. If you buy them you will need a setup that can accommodate them.

The original design called for 8417 tubes but these were modified to run 6550s years ago. This was not an uncommon practice when the 8417 went out of production and is actually considered an improvement by most people.

There are a couple of cosmetic flaws -a half inch long deep scratch in one plexiglass meter window and one meter needle calibration screw that adjusts the needle precisely to the zero db mark has been lost.

They are 55 lbs each and bulky. Packing and shipping will be expensive and local pickup is encouraged.  Shipping to continental USA and Canada only.

Thanks for looking.
