Bacup, quite a sleepy outpost! I reckon they are nicked! I wonder if the seller can demonstrate lol!

I have to say there is a lesson here, in that you have left yourself open to fraud by listing one thing and doing another! I am not really surprised paypal took side with the buyer... I think I would have politely declined in this instance, or relisted with the new price and new terms. So really there is no reason to hate either in this case but only

I am sure Martin will come along with a recomended match but in the meantime try this site... http://alltransistors.com/ Also Mouser or digi-key for components although usually worth a large order to get free postage. as far as capacitors you will more likely struggle with 3000 but 3300 should be fine..

Sounds silly but have you checked if the belt is still attached? hahahahah look at my post count :) *2nd edit I didn't realise my edit would move my count on :(

You should suggest Peter that the 4000 could potentially be far more difficult to fix than the later 400x, but yes I think it is my favorite from a design point of view!

Yes that is the relay! Remove the plastic cover and wipe the contacts using a thin piece of folded paper dipped in isopropyl (carefully press the contacts together and pull paper between contacts) and see if there is any improvement...

Hi Rich, Mouser are superb :-) Tbh doesn't sound like the trimmers are at fault if replacements haven't cured the problem... You maybe need to start by checking if you have a nice stable supply. Does the motor run freely? Hmm also have the replacement trimmers mean't the 45 setting can now be adjusted to its proper speed and beyond? Is 45

Hi Geoff I currently have a 6000 which is fine in every respect but you are welcomed with a thud at standby 'on'. I cannot see how this can be reduced, due to the fact we are dealing with a single rail supply whose mid operating point (at the amplifier output, about +30v to ground) is isolated via those large capacitors. Those capacitors on

I wonder if faulty and segments stuck on?

I am sorry Lee, I knew about this thread and completly forgot to vote! I honestly thought there would have been many people voting and am absolutely shocked by the lack of response! I think the email system might have put people off a little, if you could have a little box to enter a user name that would have gained more results maybe...? Also a countdown
