This is my first recap of an amp and I'll be doing it in pieces or segments of parts as I don't have enough to buy all the parts right away.
I thought I would start off with the parts that have the most problems first.
Which are the 150 ohm fusistors and 470uf caps on the poweramp board. I used Gemcon capacitors which specs and measurements wise are comparable to the Panasonic caps everyone else uses.
Unfortunately I couldn't get the glue off the PCB, I tried using nail polish remover (acetone) and a guitar pick to scrap it off, but 37 year old glue is strong. I also found what looked like blood is actually burnt or corroded glue, I managed to get that off at least.
If anyone has any idea what to use to take the glue off, please tell me.
Does anyone also know of a drop in Cap replacement for the two large 4 pin caps? Because the Panasonic model everyone recommends no longer exists.
I've just ordered Nichicon KZ Muse series caps for the 220uF,100uf, 100uF bipolar, and 330uF caps on the power amp board, turned out to be cheaper than buying the Gemcon caps locally.
I'd also like to endorse the Weller SP25 soldering iron for working on electronics. After trying multiple third party brands from princess auto and a few mastercraft irons, I found the tips to be disintegrating after only a few uses. I've used this Weller one for this amp and two turntables and the tip hasn't worn at all also the rubber handle and really useful LED's are a nice touch. Not to mention the plethora of tips available for $6-$8.
