These Mark III’s have just been completely gone through and had numerous updates to improve reliability, but these amps have not had any audio path mods, hacks, or “hot rods”, and remain true to the original Dynaco sound and character. The Quad caps are brand new, replaced with the upgraded versions from Dynakit, The coupling caps and bias caps were replaced. The old selenium rectifiers were updated with modern parts for better reliability. The rectifier circuits have had updates to extend the life of the rectifier tubes. The input jacks were replaced with new jacks and the old screw terminals were upgraded to binding posts. These amps have also been upgraded with bias balance controls. This update allows the bias to be setup properly for each tube and eliminates the need to have perfectly matched output tubes, allowing for greater flexibility if you want to experiment with different tubes. Amps come with: New 5AR4 Shuguang rectifier tubes (arguably the best new rectifier available today). 1 amp has a vintage National 6AN8 and the other a Dynaco branded 6AN8. The output tubes in both amps are vintage RCA 6550′s. They sound, and work, great. Cosmetics are very nice, I would say above average. There is some very small pitting on the chrome chassis of both units, but overall the chrome still looks very good and has a nice shine. The cages look great. The cages are included, so is the original manual. I have the original “Black Cat” coupling caps I will include if you want them. Interested buyers are welcome to come demo these amps and hear them in person.

We hope you enjoy the photos and information presented herein. If you have any questions. The Sunn 200S model has a simple all tube design. Basic volume, treble, bass and a low and high boost switch make this amplifier straight forward but powerful and has a beautiful natural tone. This amp is powered by two 6550 tubes delivering somewhere between 60-75 watts of output. If you want that classic Mountain growly-bass sound, this is the amp that will deliver it. Depending on the cabinet you run it through you can get a bevy of different tones that have different classic vibes but is always all Sunn. When pushed through a 4×10″ or 4×12″ you can get some of that classic Marshall 50w crunch but a little bit more warmth and fatness. Through a bass cab, something with substantial sized speakers, you can get crazy fat tones that are bone shattering. There is one Dynaco transformer, and the other seems to be a correct replacement, it has a part number shown in a close-up photo. The 6550 outputs are matched, and the pres are not, there is one Tesla E83CC, the other is a Sylvania 6922 type, they work well together here. Issues are all cosmetic, it sounds incredible and looks like nothing else out there with the vintage hexagon patterned cloth grill and 50 years of age leaving the surfaces with relic type antiquing. There is no back panel. Two screws are missing (see underside shot). There is oxidation on many of the hardware elements, and to the transformers (the non-Dynaco type in particular). The bass knob is a replacement (and is missing the chrome trim), as are the rubber feet. General wear and tear. _gsrx_vers_827 GS 7.0.13 (827).
