    Hi all, I have a Pioneer CLD-S104 Laserdisc/CD player that is not turning on at all. It hasn't turned on ever since my house experienced a power surge years ago and I've left it in a closet until now.

    Pioneer SX-60 connectors. Help.

    Pioneer CT-f2121 - easy to repair?

    Hi all, I’ve wanted to buy a Pioneer CT-F2121 for awhile now. Saw one with the wood cabinet for sale for $200. It’s in great cosmetic shape and works, but the rewind is broken. Wondering how hard these units are to repair, and whether that price is too high. Prices for these 70s tape decks have...

    Pioneer SA-710-II troubleshooting

    Hi My old Pioneer SA-710-II made a lot of noise, hum and pops, even when there were no music playing. The relay were also clicking right away when it was powered up, which resulted in a huge pop, when the power was turned on. I thought the problem was some bad capacitors so I ended up replacing...

    My RB-980BX was stuck in protection mode. I checked every component on the circuit board, replaced a couple of resistors that were slightly out of spec and replaced all the smaller caps.

    Pioneer SX-1080 + KEF 107s - bad idea?

    Any thoughts on is this a bad speaker / receiver pairing? I've seen mixed feedback but it seems most would say the KEFs are super power hungry and ideally would be used in a separates setup with a power amp pushing 300 w/ch. I've currently got my 1080 pushing Bose 901s (also extremely power...
