Do i just replace all the brown mallory caps (11 in all) , or do I replace the silver 150mf ones (5 of them) as well? I have a '75 210 sixty-five | ||

OOPS-didn't see this one first. DON'T replace the brown caps. Only do the long silver ones. Remember, the most important ones are the bias a filter caps. THe filter caps are under the "doghouse" cover on the other side of the chassis. | ||

Ah - they are the ones that can kill me right? Can you give me a simple and safe method of draining them before i do anything silly? | ||

Make a 10k-1 watt resistor with two wires on the ends and a gator clip on each end. Clip the one end to the chassis and clip the other end to the "+" side of the filter cap. Wait 2 minutes and check with a voltmeter to make sure it's safe. Leave it hooked up while working on it as caps sometimes have a memory and kind of re-charge a little. Just remember to UN-hook it before you fire the mutha up. Mike. | ||

will do - i really appreciate all your advice man! I'm looking forward to hearing the amp when its all done (speakers, tubes, caps and bias)! | ||

It actually doesn't sound too bad with just a rebias, the old tubes, the old caps and 15inch/tweeter p.a. bin. I'm not selling my boogie just yet tho... | ||

Filter caps are in. Heaps more volume. I still need the150uf caps for the topside, but postage to Australia is a killer! | ||

Okay, finally done the lot -caps, tubes etc. One more problem - i have jus trealized thatthe speakers which i spent big money on (reconing the orginals) suck. I want new ones. I ran it thru a jensen c12 and the amp itself is awesome. PS - big thanks to Mike Kaus for all his help! | ||
