    SX-1980 Quartz Lock Issues

    Please help me identify this Grado cartridge

    Thanks for the tips. I ended up buying a Gold 2 stylus to replace the black. Works great with the old body.

    SX-1980 Quartz Lock Issues

    I forgot to thank you guys for helping understand how all this works. You have been extremely helpful in me keeping my sanity! Ha! I fuss and worry about small stuff with my vintage equipment way too much!

    SX-1980 Quartz Lock Issues

    You are correct, the “compressed air” is one of those electronics dusters I get at Costco in a six pack. Gets extremely after using for so minutes. So it sounds like when I briefly change the temperature by spraying down in this section, which is why it locks and then unlocks once it heats back up?

    SX-1980 Quartz Lock Issues

    Thanks for info. I found the adjustment and made a few small turns both counter and clockwise I ended up getting it to lock and stay on for a awhile but maybe after about 1 or 2 hours it started to drift again and I couldn’t get it to lock. When I shut it off and wait 15-20 mins, it locks as...

    SX-1980 Quartz Lock Issues

    Is it possible to bypass or turn quartz lock off? It’s not essential to the FM being able to work properly, correct?

    SX-1980 Quartz Lock Issues

    Looks like I’m gonna be lugging this beast about town once again! Hopefully it won’t be too difficult for the tech that’s close to my location to do the necessary FM work. Sounds it may just need some slight adjustments.

    SX-1980 Quartz Lock Issues

    So I took a can of compressed air and blew down into where the FM tuning fins, etc reside, without removing the cover, and every time I did that, when the fine tune was flickering, it almost instantly stopped and quartz locked. After awhile it would unlock and start flickering again and I would...

    SX-1980 Quartz Lock Issues

    Thanks all for your assistance. I will give macyjrm’s suggestion a go. Please excuse my ignorance, but can you perhaps upload a pic of the tuning condenser and the points on the shaft to apply cleaner?

    SX-1980 Quartz Lock Issues

    Unfortunately, I’m not able to take it to the person who did the original alignment as he’s in NY and I’m CO. I understand that doing a full alignment myself is just not possible, for a multitude of reasons. I was hoping there was something relatively simple I could do with the quartz lock...

    SX-1980 Quartz Lock Issues

    I made some extremely minor adjustments to the slot screw labeled “TC” in section next I to FM, which I believe to be the quartz adjustment. Didn’t really do anything other than move the tuning meter needle a little and make the fine tune less/more sensitive.

    SX-1980 Quartz Lock Issues

    I recently acquired a 1980 that was fully cleaned, power supply rebuilt and the tuner supposedly aligned. The unit works and sounds great, however the quartz lock will not stay locked. Usually, right when I power the unit on, the quartz lock works as it should. After about 30 min to 1 hr give or...

    Please help me identify this Grado cartridge

    Thanks a bunch! Was driving myself crazy trying to figure this out. If I'm understanding you correctly, I can install a Prestige Gold or Silver?

    Please help me identify this Grado cartridge

    Hello- stumbled upon this thread when trying to determine which Grado cartridge I have. I picked up a Pioneer PL-530 and it came with a Grado. Can anyone tell me what model this is? Much appreciated.

    IC Chips needed for SX-1280

    Thanks all for the help with this. Unfortunately, I'm traveling for work this week (Sun-Weds) and I won't get an opportunity to work on it until I get back Wednesday evening. I will report my findings and/or progress once I'm home and able to get back to back in the music cave. Damn job getting...

    IC Chips needed for SX-1280

    Thanks. We just tried this with both of the tuning meters. The original one and the replacement I got from a donor unit. Not moving. Tuning dial stuck in the middle. Signal meters work great and radio works. What actually controls the tuning meter?

    IC Chips needed for SX-1280

    Well, I'm not exactly sure what's causing my issue, to be honest. Based on my "Internet forum" research I thought maybe the chips were the root of my problem. The receiver sounds great and operates well except for the tuning meter. The meter dial seems to be stuck straight up in the middle. It...

    IC Chips needed for SX-1280

    Thanks! I saw those PA1001A's from China on eBay but I wasn't sure they would work since there's really no description. I will order a couple of those. I do have an SX-780 and an SX-980 with similar looking chips. Do you know if these are the same as what's used in the 1280s?

    IC Chips needed for SX-1280

    Hello- I'm in need of the near impossible to find IC chips for my Pioneer SX-1280. Any AKers out there have any and are willing to sell? Parts are PA1001A and PA1002 Thanks all
