Good call on those bias trimmers. I've rebuilt more than a few of the early Pioneers, and about 40% of them come to me with bad bias trimmers and shorted outputs. Love the sound. I have an SX-2500, which I won't be parting with.
They certainly do. I was going to give this one to a family member but she passed away unexpectedly. Now, I don't know if I want to hang onto it or just sell it and get it out of the house.
Hi Wil, Excellent vid! What is the frequency of your Ultrasonic cleaner? I have damaged some solid aluminum knobs using an ultrasonic cleaner that is 40kHz (55c for 20 min) and read that you need 78kHz for aluminum.
