Amp will not power off


Hey folks,

I have owned a Forte 1A class A 50 wpc SS amp for several years that has been working great until a few days ago.

I have used a Bryston BP26 preamp with it for a while until about a month ago when I bought a hybrid tube preamp (Black Ice Audio F360).

The F360 has been used quite frequently during this month.

A few days ago, a friend brought over a Melos tube preamp. We hooked things up and listened for a few hours.

After listening for the evening, I flipped the power switch on the Forte 1A to the off position but the LED stayed on and the amp did not power down. 

Waited a while. Then tried toggling the switch a few times but eventually had to just pull the plug from the power supply.

Anyone experience this? Hope it's nothing serious.

Thanks!

Good on replacing the switch, as even though fused it's no longer safe to have in the power circuit.

Not me buddy, but I sure wouldn't mind one or two. :-) You can sure see the Pass design. I have a few Pass designs here. Threshold, Adcom, Pass, First Watt.

I've known a few Forte fans, I've seen them really hot rodded too. The can really put out the watts. Fry eggs on them too..:-) Threshold heat wise, are close.

???! That so. Do tell.

Just curious. Which Melos preamp. I was good pals with the company and don't hear them mentioned that often.

@dynamiclinearity - it is a GK-1.

Never had a tube preamp. Was always wanting to try one with my SS amps. This was a fun experiment. It was only for a few hours but I noticed differences. More with some songs than others.

I know this preamp is probably not considered too hifi but was good to experience different components.

He also brought over an old Golden Tube Audio SE-40 amp. That was also nice to try. Noticed the biggest difference sonically with my old B&W Matrix 801 S2s. Also hooked up my LRSs and then my Harbeth SHL5+40s. The B&Ws sounded less "harsh?" in the high frequencies. Maybe some less detail but a nice texture.

Really would like to try some higher end tube components.

I guess even for a novice like me, it is true that listening is really important. Sure, reading reviews and checking measurements is cool to do. But there is no substitute to really listening to a new/different component in your own familiar system, in your familiar listening room.

Doesn’t cost anything but your time.

And fun too!
