Don’t miss out on this opportunity to own a piece of audio history. Pioneer SA-8800 Integrated Stereo Amplifier (1979-81). The SA-8800 has the impressive feature which is the NSA (non switching amplifier), created specially by Pioneer. This is a type of amplifier that adopts the merits of both class A and class B amplifiers, and it excels in keeping down the heat loss and allows the transistors to operate all the time in the active region. For this reason, a high output power with a very low distortion factor is yielded all the way up to the high frequencies. Power output: 80 watts per channel into 8? (stereo). Frequency response: 5Hz to 100kHz. Total harmonic distortion: 0.05%. Input sensitivity: 2.5mV (MM), 150mV (line). Signal to noise ratio: 90dB (MM), 110dB (line). Output: 150mV (line), 1V (Pre out). Semiconductors: 3 x IC, 6 x FET, 73 x transistors, 49 x diodes. Dimensions: 453 x 155 x 425mm.

This vintage NAD 7140 receiver has undergone recent servicing, testing, and is now in working order. It is a high-quality product from Japan that is perfect for vintage audio enthusiasts. The brand is NAD, with the model number being 7140. The receiver falls under the category of Consumer Electronics, Vintage Electronics, Vintage Audio & Video, and Vintage Amplifiers & Tube Amps.

When new, this amplifier was built from a kit. I found the ad (photo #9) in an Allied Radio catalog for 1958. In those days phonographs and even FM tuners were monophonic. So this amp has just one channel. Your signal source can be mike, tape deck, or phonograph. Many choices of input and equalization are available. Output to one hi-fi speaker with impedence of 4, 8, or 16 ohms. For the demo video an RCA 45 changer is shown, but only the amplifier is for sale. The amp has 6 tubes and the clean output power is 18 watts RMS. Photo #13 shows the tape out jack and access hole for V1 on the bottom. #11 input jacks; #12 speaker terminals.

My great Uncle was in the recording industry and often received gifts from other artist. He loved gifting my Father with stereos and record players. My Father recently had this Fisher 500 C serviced by one of the best HI-FI service/repairmen in NJ EBC Electronics. Pictures show all functions, tubes and burn in no smoke just tubing. The Fisher 500-C features a full function pre-amplifier section with twin phono inputs, auxiliary input, monitor input and tape input (for direct connection to the tape head). The Tuner section features a multiplex FM system with mono and stereo options. Power output: 30 watts per channel into 8? (stereo). Frequency response: 25Hz to 25kHz. Total harmonic distortion: 0.7%. Input sensitivity: 3.3mV (MM), 450mV (DIN), 230mV (line). Signal to noise ratio: 80dB (line). Channel separation: 50dB (line).

This wasn’t serviced as it seems to be working just fine. Without even using an external antennae the unit pulled in local stations. The cat’s eye tube is working and is very cool.

Here we have an amazing and LOUD bogen challenger 75 watt tube amplifier. It’s been treated to all new electrolytic and coupling capacitors replaced with quality film capacitors. Out of spec resistors replaced.

Unit has been fully cleaned and tested for over 8 hours and all aspects function properly. All 4 output have been replace w/quad matched set of KT77.

I bought this piece all dusty and without been used for years from a garage sale a few years ago, it had one broken tube. I’m adding pictures of the old capacitors, the old tubes (two are MULLARD Fat Brown base EL34 Xf1 still good and the other two are old xf2 black base EL34 tubes), the receipt for the service and a Manual I print out.

The cathode bypass electrolytics were replaced in the preamp section as well as one of the power amp sections. The cathode bypass resistors were replaced with 200 ohm 10 watt parts to increase the cathode bias to 95% and it sound much better like that.

We located in Northern California. 26 x 10 x 14.
