Vintage Tube Amp

This Dynakit ST-70 amp is fairly dirty from sitting in storage for so long. I have no idea when it was last used. It’s been modified with some gold RCA connectors, and there may be more mods under the chassis. Please note that the EL34 tubes that are included are not Mullards, but rather National that claim to have been made in Germany. My guess is that they were made in Russia. No GZ34 is included, nor is a cover. This one will make a great parts unit or candidate for restoration. This piece of equipment is believed to have not been used in years (possibly decades). It will almost certainly need some level of service. This may include: replacement of electrical components (such as capacitors, resistors, diodes, tubes, etc), cleaning of controls, alignment, and so forth. If you’re not qualified to do this work yourself, we’re happy to provide you with a list of qualified technicians available for hire. If you prefer one carrier over the other, please make that request when paying for the item. Rest assured, you’ll receive your item in excellent condition!

Vintage Dynakit ST-70 Stereo Tube Amp Power Amplifier UNTESTED. Looks complete with all tubes and knobs. Missing the bottom metal plate & cage. Info found on the web. The Dynakit Stereo 70 is a complete dual 35 watt power amplifier kit which offers the highest possible fidelity, at low cost and in a compact arrangement. It uses a patented circuit of outstanding performance characteristics, along with top quality parts, including the new Dynaco Super-Fidelity A-470 transformers – the finest available. The measured specifications show that the Stereo 70 is an amplifier of unequalled performance, and its listening quality is also unrivalled by any regardless of price. The two non-interacting 35 watt channels provide adequate power, in a stereophonic or two channel system, for loudspeakers of any level of efficiency. The channels can be paralleled for a full 70 watts of low distortion output, suitable for practically any monophonic use even where several loudspeakers are in use in different areas. The high power capability and low internal impedance provide excellent damping for all types of high quality speaker systems without need to make adjustments to match specific speaker installations. The design features of your Dynakit which contribute to its superior listening quality include some which are not revealed by the customary steady-state laboratory measurements. For example, it does not exhibit bounce and flutter when pulsed with a transient signal. Thus a sharp percussive signal like a drum beat or a piano note will be reproduced with sharpness and clarity and neither overhang nor muddiness. The Stereo 70, unlike many other amplifier circuits, has been designed to provide its specified performance on a loudspeaker load, not just under laboratory measuring conditions. Therefore, the connection of a loudspeaker to the amplifier does not deteriorate its performance or listening quality. Power output: 35 watts per channel into 8 (stereo). Frequency response: 10Hz to 40kHz. Total harmonic distortion: 1%. Input sensitivity: 1.3V. Signal to noise ratio: 90dB. Speaker load impedance: 4 to 16. Valve complement: 4 x EL34, 2 x 7199, 1 x GZ34. I do not have the proper equipment to test a tube amp and do not want to risk applying power to a 60 year old unit. Previous units that I acquired from the same audiophile collection have proven to be in very good condition. He did not own junk. See pics for details. Will be carefully packed in a sturdy box with ample packaging. On all 6 sides. The Last pictures is an example of how I pack these (with Styrofoam on the top and bottom as well as the sides shown).

Vintage PAIR Dynakit Mark Mk IV Mono Tube Amps Amplifiers UNTESTED Minus 2 Tubes Looks complete except for 2. Tubes on one of the amps. Info found on the web. The Mark IV Amplifier uses a circuit arrangement based on that of the Dynakit’s Mark II and Mark III which have become world famous for superior quality while essentially simple and trouble free. The new 7199 tube is used as a pentode high gain voltage amplifier directly coupled to a cathodyne phase inverter. All parameters are adjusted for minimum distortion. This type of phase inverter has the unique advantage that its operation is independent of tube ageing so that no adjustments are required in maintaining optimum performance. An internal capacitive feedback loop balances the phase inverter at the highest frequencies, and the arrangement provides accurately balanced driving signals to the output tubes, which are EL-34′s operated well below their maximum ratings. The output tubes use a fixed bias arrangement which is set through use of Dyna Biaset (patent pending) which provides optimum linearity of the tubes and minimizes the effects of unbalanced components. The connection of the output tubes includes a small percentage of screen loading which improves the regulation of the output stage and makes it comparatively uncritical of load impedance. Power output: 40 watts into 8 (mono) (EACH). Frequency response: 20Hz to 20kHz. Total harmonic distortion: 1%. Input sensitivity: 1.3V. Signal to noise ratio: 90dB. Speaker load impedance: 4 to 16. Valve complement: 2 x EL-34, 1 x 7199, 1 x GZ-34, 1 x selenium rectifier. Dimensions: 5 x 14 x 6.5 inches.

This compressor came from a California engineer who is in the process of downsizing his massive collection. He had removed it from a local station approximately 20 years ago. Since then, it’s sat in his radio room as a display piece. From what we can tell, it’s complete and all original. It’s a little dirty from years of being stored in an open-air rack, but should clean up well! The unit will have to be recapped before it can be used, and other components (resistors, etc) may need replacement as well. Also, we cannot guarantee the life of the tubes as we have not tested them. The tubes will be removed and boxed to ensure they reach you in good condition. This item will be packaged using our InstaPak foam-in-bag system, ensuring the utmost protection! Bags filled with a chemical mixture expand around your item and harden to form a protective, yet forgiving, foam barrier. IMPORTANT: You will only receive what is photographed.

This amplifier looks pretty good. The faceplate looks great with practically no wear, and the cabinet looks good with only a few scuffs and a bit of white paint on the top above the transformer (see photos). The chassis is a little dirty, but would clean up well. All controls turn smoothly. This will make an excellent candidate for a electronic restoration! This unit is believed to have not been used in many years, likely decades, and with this in mind we have made no attempt to power-on this unit or test in any way. Unless you are qualified and capable of working on this unit yourself, or are willing to pay a qualified individual to do the work for you, we suggest you revisit the idea of whether this is the right equipment for you.
