Poweramp re-cap etc...
« on: June 01, 2011, 11:10:21 am »

Here is an amplifier I have been "servicing". I have LM4562 on the input board, replacing 5532, Panasonic/Vishay BC/Nippon Chemicon recaps (BC's to do + resolder that wire I broke :-\)

Ceramics to NP0/C0G x 6

It seems quite an uncomplicated affair for an amplifier and in part I think this might be partly why it sounds so good.

Look forwards to switching it on and testing on a speaker I do not mind being destroyed in case !

My friend recommended the amplifier 250RMS per side and it sounded quite good despite it's 14 years age. Bit of evening fun for me. :D

With only a 25W iron that was a real ball ache trying to get the last 2 large caps off but I managed by letting the iron cool off sufficiently for 25 secs or so. All done ! Just need to do QC and brush the boards down and clean the case up inside.

Just got to sort a couple of manky varistors on the main input board and this will be good to go.
Awaiting purchasing those in case I will be modding a new compressor I have purchased. I will see how it fair's stock and take it from their. It supposedly dark which will be a nice companion to the DCL-200 which is not bright but passes what comes in faithfully.
