    Restoring and Cleaning Amplifier Internals

    I've come across a Pioneer SA-510 that was kept in the garage as an amplifier. It started "acting weird" so it was given to me. I respect the vintage tech, and want to bring this thing back to life for normal use in a cared for environment. It's got 2 problems. It is oxidized inside. Rusted on...

    An observation about tribal lore for cleaning pots

    The popular opinion is to soak the heck out of the pot with DeOxit, swish the control many times side to side, then rinse to wash out the "gunk". And to be fair, that does seem to work pretty well. I now use a method told to me using the needle version of DeOxit and a more targeted way. The...

    Newbie Cleaning Question - Anything I should NOT touch inside?

    I'm about to clean the pots and switches following the AK "Idiot's guide to DeOxit" but before I start is there anything in there i should definitely NOT touch?

    Why flooding speaker et al switches may not work well

    Dribbling DeOxit down a Marantx speaker switch or one of the many others is a time honored tradition for us that restore these beasts. But, if you take one apart, you will find that is probably not the best way to fix them. That is assuming that A: you have a newer switch and B: you don't mind...

    Alcohol leaches plasticizers in vinyl and alcohol cleaning record cleaning FUD

    Every time I post somewhere about cleaning records (the solution I use was recommended by the manufacturer of my RCM and is isopropyl alcohol, water, with a drop of dish soap) invariably someone responds with the claim "alcohol leaches plasticizers from vinyl". I find this claim dubious, but I'd...

    Hey all, A while back I posted about a tech I had work on my 4400 and when I asked him about how he went about cleaning controls on the units, he told me he did not like Caig products and instead used something called "Tri Flow Lubricant".
