Vintage Tube Amp

The Dynakit Mark IV Tube Amplifier is a vintage model known for its high-quality sound and classic design. As a well-crafted piece of vintage electronics, this amplifier falls under the category of consumer electronics and vintage audio & video. With its Dynakit brand reputation and tube amplifier type, this model is sure to appeal to audiophiles and collectors looking for a piece of audio history to add to their collection.

Please note there are minor scratches and marks due to age. Please note that it is a used item. Kindly refer to the product description for more details. If you have any questions, please feel free to ask.

Still needs a bit of work. All transformers work as they should.

A new grounded power cable added and both units tested and working AS IS. These may benefit from a full recap. There is wear from use/storage like scratches, scuffs and dust. 1 x Sylvania 6BQ5. 1 x RCA 6X4. 1 x VM Mullard? 1 x Heathkit Mullard? 1 x VM 6X4. Please contact me if you have any questions.

This vintage MAGNATONE Tube Amp from 1958 is in good condition with some light wear and tear to the edges. The handle is broken. It has been tested and sounds great!

Scott Stereomaster 340 Receiver. Up for sale is a A rare used 1963 H. Scott Stereomaster 340 vacuum tube MPX receiver. All tubes were tested and they are good to N. The original four Amperex 7591 tubes test excellent at 8,500-9,250 umhos. Controls work but there is switching crackle in some. The unit is in excellent cosmetic shape with a few small marks that are shown in the images. The plastic tuning dial is missing. With the bottom cover off, everything inside looks original to the factory design. This unit does partially work but will need work to bring it back to factory spec. I have included a fairly hard-to-find owners manual and schematic for this unit. This is a highly sought after integrated tuner with great build quality. With some TLC this will make the centerpiece of a fantastic stereo system for someone looking to explore tube audio. The unit is very heavy and will be packed safely. I will pull some of the tubes and pack them in tube boxes.

This is a used Lux vacuum tube amplifier that has been tested. It requires four 6RA8 vacuum tubes to operate (not included). Deteriorated components such as capacitors have been replaced. The main unit has scratches and rust, but there are no severe stains or dents.

Console pulled The Fisher 460A vintage EL84 tube amplifier approx late 1950′s or early 1960s (See label and serial number in photos). This amp has been fully restored electronically w/ modern capacitors + modifications to account for fact that stereo tuner is no longer present in the console, thus a bias resistor modification is made to properly bias the tubes (See 20 watt gold power resistor mounted to underside chassis). All capacitors and components are top quality such as Nichicon electrolytic and classic “Orange Drop” coupling caps, etc. The original top-side “MULTI-CAN” large capacitors were left in-place for vintage aesthetics while all new capacitors for the DC tube supply voltages were built into the underside as shown in the photos. New rectifier diodes were also installed as shown. A thermistor was added to the A/C input side to soften start-up current surge to the tubes and also add slight voltage drop to account for higher line voltages in today’s homes. The tubes are (2) Sovtek EL84 + (2) Russian 6P14P (EL84) for the power output + (2) 7247 for input stage : The amp, since it hadn’t been run in a while was “burned in” on the bench for approx 2 hours and ran perfect. I re-checked the bias and supply voltages and everything was in-spec. No hum, no sound issues – it’s running great. I will include a marked-up schematic and an original un-marked schematic to show the modification(s) and resistor values performed and needed to make these Fisher console amps run properly in stand-alone mode as was done to this one. An ON/OFF power switch was added (it appears the green LED light in it is out, but does not affect the power switch function). There is also a custom mesh steel plate bottom w/ plastic feet that was added allowing proper ventilation to keep the tubes running cooler. The bottom plate is steel – I left it un-painted as a new owner may want to paint it a custom color or build a wood case for the amp etc and thus it shows a bit of light surface rust as it’s not coated at this point. This amplifier is intended for a vintage tube amp collector or similar who is fully aware of what they are looking at in the photos and how to safely handle a tube amplifier if they remove the bottom cover etc as dangerous voltages are present.

Vintage circa 1960′s SCHOBER Transistor Guitar Amplifier TR-2 range of 4-16 ohms 117 VAC. Good vintage condition overall, typical age wear on body but no dents or dings, no missing knobs or dials, power tested and turns on and fan runs (makes a squeaking sound) otherwise untested with use, see photos. Please see photos for closer details and if you have any questions please don’t hesitate to ask.
