Dynaco Stereo 70 Amplifier (Tested/Serviced) Original Caps / Selenium Rectifier

Description: This is fully tested and working great. All tubes are tested and very good. The only 2 items that are not 100% original ( other than the tubes ) are the RCA inputs and 2- 10 ohm ground resistors. The bandwidth was professionally tested and both channels are flat from 20-20KHz. It does have some signs age and use, some minor pitting on the base, but still very presentable and not butchered up or modified like the majority of ST-70's out there. Please look very carefully at all the pictures for its exact condition.Dynaco Stereo 70Stereo Power Amplifier (1971-17)DescriptionThe 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.This amplifier has characteristics and power rating ideal for either stereophonic or monophonic use. 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.In addition, due to the high quality of the output transformers used, the Dynakit's power handling capabilities are maintained over the entire audio band without the sharp rise in distortion which characterizes most amplifiers at the extremes of high and low frequencies.Power output: 35 watts per channel into 8Ω (stereo)Frequency response: 10Hz to 40kHzTotal harmonic distortion: 1%Damping factor: 15Input sensitivity: 1.3VSignal to noise ratio: 90dBSpeaker load impedance: 4Ω to 16ΩValve complement: 4 x EL34, 2 x 7199, 1 x GZ34Dimensions: 13 x 9.5 x 6.5 inchesWeight: 32lbsFinish: nickel plated chassis, charcoal brown vinyl paint coverChasrock Services is proud to be: ( ISTA 6-FEDEX_A Protocol Certified ) This is a registered certification in electronic packaging. We are approved to safely ship any electronics up to and including 150 lb. packages. The ISTA 6-FEDEX A Protocol is an earned certification. This is achieved by packaging and shipping electronics to the FedEx packaging laboratory, in Collierville, Tennessee They put that package through rigorous testing including the following: Shock Test: (10 random drops from 30 Inches) Compression Test: The package is then tested in a press at 976.94 lbs. of pressure. Vibration Test: The package is then put on a vibration table and violently shaken for 45 minutes. You must pass all three tests without any damage, cosmetically or functionality. This will be double boxed, surrounded in foam to insure safe undamaged delivery to your home or business. Yes, the shipping cost is a little high, but electronics are fragile and do require a lot of packaging and time to get them done right. I think it's worth a few extra bucks, because they can't be replaced. A note for you eBay global customers: ( I will get it to your door safely and insured.) P.S. My posted shipping price is always the total! I pride myself on extreme over protective packaging. (Please see my feedback!) I will only ship to the 48 contiguous states and I encourage eBay global shipping. Payment is expected in 48 hours of purchase and on the same token they will ship on the next business day. If you need more time, just send a message and we will work something out.
