Re: Sherwood Amplfier

Sounds like you like your music like me... LOUD. If you've done this a number of times, there are a few things that can happen:

1. You've blown the speakers... but you've said it operates for 2 seconds, then cuts out.
2. You've damaged the amplifier modules within the amp and they immediately overheat upon power-up. Does the music come back like 5 or 10 seconds after the unit cuts out?
3. Thermal switch has malfunctioned and just cuts off the power to the amplifier modules as soon as it sees any heat.
4. If you've gotten the amp really HOT during playing, it's possible that it's as simple as the amp modules are only intermittently connected (fatigued/stressed or cold solder joints) at the on the PCB. Just resolder the connections of the amp module to the PCB. I've seen that happen numerous times and that's where I'd place my money.

Amplifier shuts down soon after turned on with a "click" sound. This happens intermittently but less common in cool weather. Nothing is placed on it and it is in a relatively dust-free...

Hi, This is a (thermo switch) heat is being generated through the unit. This switch turns it off when the amp gets to hot. My suggestion is you can place a fan near the unit to cool it down. Good luck.

I have a Sherwood Nottingham R-925RDS receiver. No matter what input I select it does not connect to the amplifier section. Everything else appears to function ok. Unit switches on & off, correct...

Let's work with FM as that is ONboard and can't be connected wrong. Does THAT work?

Turn the volume control to something medium.

The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

My sherwood r525 only plays preamp and i was wondering how to fix it

I have the manual for the Sherwood R-925 and I think they might be simlar in design. It's says for this problem check transistors Q215 and Q216 on the AMP302 board.
Of course you will have to determine if this can help solve your problem. I think the model you have is just the dolby surround model and the 925 the dolby digital, but they look nearly the same I think!

Amp power outlet

Ususally this fuse (if there is one) is located near or in the socket. Unfortunateley I don't have a photo to discribe to you, but it might be under the black counterclockwise cap or at one square area just under (or above) the socket.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

Hi fi wont turn on !

hi. im assuming its a technics / panasonic system judging by the F 61 error code? try testing the cooling fan at the rear (assuming it has one) i once had the same error code on my technics amp and it turned out to be a faulty cooling fan. after replacement out of a scrap unit, the amp worked perfect.

Amplifier power cutting out

not enough power to amp and or amps location is too hot might want to invest in a couple cooling fans from computer store and attach where needed

an amp should take up to 3/4 load but when not enough air to it to cool it off it will shut down

try this turn gain all the way down and slowly work up too desired amp volume setting

SU-V460 cuts out at high volumes

Hi samipoyo

You need to check the amp for dry solder joints about the output stages. These amps are notorious for soldering going bad. I would set about re-soldering the entire output stage.

I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.
