Hello I finally got around to seeing why my Dynaco Pas 3 Tube pre-amp was not turning on, and it appears it's the PA11 transformer that has no voltage coming off the two lines that are soldered to the SDS Labs board on the underside. I did see 12 volts at the fuse on the SDS card. Any...

Hello everyone, I've got a early Thorens TD 124 that is slow to kick in the strobe lamp and start the platter, once I turn the selector on. I have replaced the belt, switch and capacitor, and it improved it somewhat but is still taking 6 seconds to turn on the strobe lamp and start turning the...

Could anyone shed any light on my Yamaha YP-B4 automatic turntable , that doesn't want to start at the proper point on the LP. The tonearm will drop a 1/2 inch in on the 33rpm LP and return to the resting place from the end of the LP to the resting arm, so that's good but also on occasion it...

I'd greatly appreciate any help in repairing my Yamaha Ca-1020's power switch, which the flip switch has broken. Can these be repaired easily, and are they possibly still available somewhere? The function of the switch still works great, just the tab is broken? I've included a similar photo of...

I'd appreciate any insight as to why I'm seeing tubes go out on my MC275 MK IV with low hours. I was just thinking one ran it's course and I replaced it with a new KT88 and it immediately started to glow much brighter than the other three and seemed extremely warm. I quickly shut it down, and...

Picked up a deep storage Nak 582 and things seem to be moving ok on rev, fast forward and play, but the door opening is not functioning from the faceplate button. I do see the clear plastic top piece of the door is not holding , thus making the alignment an issue. Also When I removed the...

My 680 does not go into play, can anyone tell me which belt I need to replace? The big fat belt seems to be running fine, the forward and reverse works fine, and the tape counter is working? What belt am I not seeing that controls the play? Also how do you get the whole transport out to fix it...

I picked up a Nakamichi 680 and fast forward and reverse all work well, the main fatter belt appears to be spinning around well, but when I press play the heads/mechanism rises and 3 seconds returns down? Is there a belt I'm not seeing responsible for the take up reels when engaged? Looks like...

Hi there, I was trying to clean the dreaded sub-harmonics switch on my HK570i, and had the faceplate off, but would appreciate any help in getting at those tiny switches again. In the meantime, after re-assembly, now the tuner doesn't work, not a peek out of it, I hope I didn't break the...

I had a quick look inside of my lovely Pioneer SX-1280 to see that the pots are enclosed in a housing so it doesn't appear like it's going to be a simple shot of Deoxit into them. Any help and suggestions would be appreciated, for I've got one that's acting up. Appreciated Ken
