Classic Dynaco MKIII Monoblocks in nice shape with cages. Amps work very well with no known issues and really sound great. This is a very common modification for Dynamos and other tube rectified amps or integrated amps and there are many threads on AudioKarma and the Dynaco Tube Audio Forum dedicated to it. According to many, this mod should be done to all tube amps using tube rectifiers, to reduce the chance of damaging the tube rectifier which is the most sensitive component on a tube amplifier. If fact, all major guitar tube amp manufacturers moved to SS rectification in guitar amps for this reason.It also allows the use of more common rectifiers like 5AR4. I have attached a schematic of the mod which is the only change to specs. So a stock pair with one common upgrade to improve reliability. I have attached the schematic for the mod that was done. Any discoloration on the tube cages in the picture are due to the fact that I had just rinsed off and towel dried the cages.
There was still some moisture present which cause the color to appear inconsistent in the pictures. That is not the case in person. This pair comes with Chinese KT88s and RCA/Sylvania everywhere else. Lots of extra tubes included as pictured. The pair also comes with a couple of.
Extras so the unit can be operated right out of the box without a full function preamp. The passive preamp is equipped with 3 RCA inputs and 2 outputs. In addition to the preamp and power cord, I have included a pair oh high quality RCA interconnects. All you need is a source and you have everything that you need.In the unlikely event that we run into problems. I will stand behind my listing and make it right even if it means taking a loss.
