Hello, I recently stumbled across one of these amps at a local flea market
and got it for a steal, at least I think it was a steal. It is in excellent condition. Anyway I was looking for some opinion and specs on this amp. I also would like to know if I should still get sound form the speakers with the unit off. I can turn it on or off and still get out put from the speakers. It's fairly common for amplifiers to continue to amplify sound for several seconds (as much as 30 in extreme cases) after their power switch is turned off. Amps which have large power-supply filter capacitors banks can store a great deal of energy in the capacitors, and this stored energy can continue to power the amplifier circuitry at modest volume levels for quite some time. [Hence, if you are working on one of these amps with the cover off, you should be *very* conscious of the fact that the caps can store enough energy to damage the circuitry, vaporize a small screwdriver, or cause severe shocks and burns. Technicians often install a combination voltage-indicator (e.g. LED or bulb) and bleeder resistor directly across the capacitor terminals, to warn of the presence of stored energy and to drain it away in a reasonable amount of time.] If the amplifier is still amplifying 5 minutes after you turn off the power switch, I'd be concerned that the switch itself is shorted and that the amp is _not_ off. If the amplifier is still amplifying 5 minutes after you unplug it from the wall... it's haunted, and you should get out of the building IMMEDIATELY and should _not_ stop to investigate those strange sounds from the basement. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
