No mid-fi, no gimmicks, no junk. Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support. This listing is for a working set of Mark VI Monoblocks in working condition. Features rare XLR inputs for an amplifier this age. Cool bias meter on the front with rack handles. This pair of amplifiers is labeled “Dynaco Wired”, however they have underwent a significant modification at some point in the past. The majority of the electrolytic capacitors were replaced, film bypass capacitors were added to the various power supply rails, and slow start relay circuits were added to delay the B+ voltages. Other modifications may have been performed that we are unaware of that sharp Dynaco aficionados may recognize. Both amplifiers were tested to their rated power of 120W. Both meter lamps and meters are working properly. Tubes include RCA 7199, and a mix Sylvania and Philips USA 8417. Please see our pictures for overall condition. The Mark VI is a vacuum tube high power basic power amplifier designed for the professional sound installer. Vacuum tubes are most often favored in their ability to withstand enormous physical and electrical abuse – conditions frequently encountered in discotheques, public address and musical instrument applications. Its rugged construction and utilization of superior components, including the patented Dynaco Super Fidelity transformers, permit continuous duty at full power, while maintaining safe operating margins. Protective isolation of the load from the driving circuits, and uniform power output into a variety of load impedances are inherent in all designs which use an impedance matching transformer. The Mark VI employs a basic circuit arrangement which all Dynaco vacuum tube amplifiers have used since the inception of the Mark II amplifier in 1955. Refinements of the operating parameters have been incorporated for circuit balance, stability, and for drive capability. The components used have been selected to protect against failure, and all parts are operated conservatively to assure superior performance and proper operation for many years. The SkyFi Testing Process for Tube Amplifiers. We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and tubes are inspected for signs of stress overheating or cracking. We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If it all looks clean we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier the remains powered on to “burn in” on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will also be tested. We also test all tubes for output gain and leakage on our calibrated modern and professional tube tester against the original manufacturers specifications. If needed, the tubes will be replaced from our vast NOS (New Old Stock) vintage or modern inventory. Final testing involves pushing actual music thorough the amplifier. We’ve learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we’re very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice. 120 watts into 8 (mono). 10 Hz to 40 kHz. Signal to noise ratio. 4 x 8417, 1 x 7199. 19 x 10.5 x 8.75 inches. We have too many items for sale and its nearly impossible to keep track of offers outside of the official system. We accept trade-ins of equal or lesser value under certain conditions. Please visit our website to submit your gear for full consideration. We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. And will typically pass on displays, projectors, receivers, dated surround processors, and mid-fi equipment of any type.

Made in England vintage 1970′s Sound City 120B 120 Watt bass amplifier head. This head is a BEAST. Have built a loyal following over the years. He was afraid to plug it into a cabinet for fear that this mighty head might blow the speakers! I have since tested it out, plugging it into a Peavey 4×12 guitar cabinet. To my ear it sounded pretty good, and did not blow any speakers in the cabinet despite its power. Having been in storage for years I’m sure it could use some work. It has six (count’em six) EL34 power tubes providing the 120 watts, three of which of the legendary vintage Mullard EL34 power tubes, which I believe to be the original tubes. Of the 3 additional replacement EL34′s one is a vintage RCA, one a vintage GE and one a vintage Sylvania, all well respected tubes in their own right. All of the preamp tubes are Brimar (again, probably the original tubes). Two Partridge Transformer, which is what these heads originally came with. One does look newer so I don’t know if that might be a replacement. I can see that at least 3 of the pots have been replaced as they don’t match the rest. Some scratchiness in some of the pots. One of the knobs in the front was missing so I replaced that one with a “chicken head ” knob, which is the style of knob used on some Sound City heads. I used to sell a lot of guitar amps on here and in the past I would have taken a head such as this to an amp tech and would have paid hundreds of dollars to have them go through the amp and restore it prior to listing it. I will guaranteee it will power on. The general consensus (from what I’ve read in online threads) regarding these heads is that they could use some mods to improve their sound and playability, although there is some dispute as to the optimum mods that might be performed. Cosmetically this head is (in my opionion) in pretty good shape for a 40+ year old head. One small nick in the front bottom left section of the tolex but otherwise no rips or tears in the original tolex. Some wear in the top tolex and elsewhere. The white plastic “grounding” switch on the left portion of the back panel looks a bit stumpy–I don’t know if there was more there at opne time. I have priced this head taking into account the need for resoration and repair and would be listing it for MUCH more were it already restored.

1980s Peavey Rock Master Vintage Tube Series 120w Amp Head. Tolex is great only real flaw is the top grill screw holes has chipping (see photo). I had her rewired and the fuses replaced with higher quality. The tubes are what were in it when i acquired it. They still have plenty of bite left, but I would suggest replacing them as they are a mixed bag, with some RCA 6L6s and the 12AX7s are a mixture of original Peavey and Bugeras. This amp is a screamer. Comparable to the classic Marshall JCM800. Original foot switch is included. I have this amp listed elsewhere as well as locally. I reserve the right to end this listing upon its sale elsewhere. I pack safe and secure. This is a rare, hard to find gem of a tube head. Do your research, read the blogs and reviews. Lowball offers will be quickly rejected. I know what its worth. The item “1980s Peavey Rock Master Vintage Tube Series 120w Amp Head” is in sale since Monday, November 18, 2019.
