Vintage Tube Amp

For restoration or reconstruction, what you will get is exactly the pieces you see in the images.

Dynaco Dynakit Stereo 70. The price includes the Genalex tubes. I’ll negotiate more if the tubes are removed. Therefore, the connection of a loudspeaker to the amplifier does not deteriorate its performance or listening quality.

Dynaco (Dynakit) Stereo 70 (ST-70). Vintage Stereo tube amplifier. Serviced: cleaned and vacuumed chassis, cleaned all controls and switches, and jacks. Tested all tube outputs. Installed replacement 7199 tube. Replaced fuse, connection at fuse holder and set bias. 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. AS-IS sale due to age.

Dynaco ST-70 with Van Alstine “Ultimate 70″ mods. This is a legendary amplifier and a piece of audio history that’s been modernized by Frank Van Alstine. The mono/stereo switch has been removed, input and speaker jacks have been rewired and replaced, and a heavily upgraded circuit board has been installed. Current output tubes are Psvane EL34B; Cosmetics are 8/10 due to some rubbed off lettering on the chassis. I live in suburban Portland, Oregon. Problems are few, and I’m very pro-active about solving any that might crop up. Please examine the pictures carefully. They are part of the description. This is NOT a new component. As such, it does not come with any guarantee– implied or written. Vintage audio equipment is sensitive and does not travel particularly well. So in rare instances, that which was working 100% at my house may require adjustment or servicing before working equally well at yours. Most on-line sales of vintage electronics happen under these exact same conditions-but I just wanted to point this out so there are no misunderstandings or disappointments. Spoiler Alert: They will NOT allow this. But please understand: I simply clicked a box making this available to International buyers. Here are a couple that my International customers have successfully used in the past and have a good reputation: Nippon Express USA or U. Both are located in San Pedro, CA. Contact info is available on-line. I’m looking forward to doing business with you and earning more of it in the future. I absolutely LOVE this stuff, and you will find me to be a reasonable, fair-minded person to deal with.

For sale is a vintage. Dynaco SCA-35 Tube Integrated Amplifier with Phono Stage. All tubes are vintage tubes; some of them are Dynaco. All tubes are included. Dynaco SCA-35 share the same transformers with the highly coveted Dynaco ST-35 power amp. As shown, the transformers are huge. This amp works and both channels produce good music. Some of the control can get cracking noise in the output. I think that’s because of the poor and aged electric contacts on this amp. The Treble control can turn forever without a limit. Power indicator lamp is out. All these need service. The amp is a good candidate for restoration. The amp appears to be all original; no mods. Physical condition is good, although there is rust in areas. Front plate does have scratches, markings, etc. All knobs are original. Bottom plate is present with feet. The screws on top covers are missing. I have other audio equipment, like.
