Neat little amp with amazing sound for it's age has a tone bypass switch wich even cut's out the balance control. Rare feature has midrange control. Plenty of inputs: 2 aux, 2 phono, 2 tape monitor and tuner. I listen to classical and the soundstage is wide and the sound is smooth. I hooked up angstrom speakers with double 8 inch woofers and the amp has no trouble driving them. I'm glad i purchaded it.



re: SA-1500

Had one of these amps for a while now, got it for cheap, sounds great love it, but I cant find anything on what the bias settings should be. Any help would be great

re: SA-1500

Looking also for the bias value but nothing found, mine stops working after a few hours and heats up pretty hard, I bet the current bias is too high.

re: SA-1500

I'd make sure the bias pot is good. If it's open, this would happen. I don't know what the bias is supposed to be, but this topology usually works well at 40mA or 20mV across one of the 0.5 ohm emitter resistors. If the "stabistor" diode is bad, this could cause the bias to be too high or if it's been replaced with conventional diodes, thermal stability may not be as good. Hope this helps!

re: SA-1500

I also have this amp, and agree with the review from allopeanut.

On mine i have connected the recent aquired JVC Zero 4 speakers, best sound i have heard so far (trial and error and a lot of vintage audio piling up).

Curious what the watts per channel are at 8 ohms?

Specs on Hifiengine say 35 watts per channel at 8 ohms, the manual says 75 watts per channel at 8 ohms?

re: SA-1500

From the manual, continuous power is 35 watts per channel at 8 ohms, 20Hz to 20kHz, 1% THD. This is broadly comparable to the modern RMS standard, although output may be a little lower as the later standards had strict testing regimes.

75 watts is the IHF rating ie maximum power output for 20 milliseconds. The practice of stating IHF power figures as the 'headline' power output was outlawed in the US in the 1970's as it was thought to be misleading customers.

Where available we state continuous power output figures. Testing methods (eg manufacturer/FTC/DIN) vary, but they are arguably more useful for comparison.
