re: A-5

Like the others, I have had the same burst of noise immediately after turning on the amplifier, but it has never affected my listening. I bought the unit, along with the AM/FM Stereo Tuner T-5, in 2001 for about $35 in a junk shop in Brooklyn; it has never failed me!

re: A-5

Thanks You very much HiFiengine site. I love this Amplifier, has an excellent sound, very real sound. You can enjoy It listening classical music. But now (after 37 years) is having a problem at the startup, It starts with a strong noise for about 10 seconds. With the service manual, I´ll have the way to check It.

re: A-5

My A5 has now bit the dust.. the power transformer secondary winding is open ..the winding for the power lamp is still good...is there a fuse somewhere in this thing for the secondary winding? I cannot find one at all accept the main fuse..help?

re: A-5

I have this amp also with the same noise problem on Startup and shut down..it is like a static sound , but after it warms a bit it goes away and works great for a little amp..I have not found what is causing it as yet..I suggest turning off the speakers before turning it on or off..
Although this amp is only 25w/c it sure seems like more to me.

re: A-5

I just bought one of these amps as I like to repair Vintage gear.. Mine was only $10 and at present doesn't work..accept it does power up. All switches are working as are the LED vu meters..no sound as yet.. maybe the Big dual amp IC is the problem.
