Well I wound up sending my unit off for alignment at The Audiowright Shop in Columbus, Ohio. It took nearly 12 weeks due to a massive backlog, but the alignment was performed. He wound up replacing a transistor that was preventing him from aligning the unit. I asked if they would just replace...

Alright, I will be taking the unit in to AudioWright in Columbus for an AM/FM alignment. Are there any transistors (Q8 and Q9 already replaced) or maybe the FET that should get replaced by him before the alignment gets done? Anything that will become problematic with the tuner? High failure rate...

Ok, I stepped away for a while and came back to it. I didn't relize how much you had to turn these new variable resistors. Everything I have checked so far is working correctly and I have put it on main power to perform the adjustments.

Ok, the power amp has been completed. I installed TTA004B in Q9 and Q10 and TTC004B in Q7 and Q8. I turned all vr1-vr4 full ccw. (Vr3 and 4 will spin freely and have no stop) the protection relay did not kick until I turned either VR1 OR 2 up about half way. I attempted to adjust neutral...

Yep, that looks like a winner right there! I am going to order a set. Thank you! Now I am just waiting on those after which I will start on the tuner. I went ahead and got the main filter caps in. They were smaller in diameter than the old ones. I just took the jacket off some romex that was...

It is already in post 10. I must let you know that I make no claim on the accuracy of the content. I will say that it is HEAVILY derived from content posted by markthefixer. Now, back on the topic KSA1220AYS for Q9 and Q10 on the power amp. Local electronic store told me over the phone they had...

Could he have had some late night "fun?"

How did someone's a$$ get close to his eye?

I think we have all have been here. I was listening to empty input noise on my Pioneer SX-737. Volume all the way up with my Sennheiser headphones on my ears. Turned through the inputs and hit FM... My hands never traveled so quickly to the power switch before in my life! Hahaha!

Everything up to this point has been going very well and I have been checking every time after I finish a board on my DBT. I am down to the power amp and tuner remaining. I am at the point where I am replacing the variable resistors VR1 - VR4 on the power amp. Let me use VR1 as an example...

Very smart! This way you effectively capture the mechanism at an extreme and can easily (in theory) replace it after the work is done. I will get some painters tape to avoid leaving adhesive on everything. Thanks for the tip! More progress has been made. The switch & volume, microphone amp, and...

Well I have been able to get some work done. Started on the power supply and protection boards. Definitely looks like someone has been in here before I was. There were some caps branded "Jameco" and encountered some semi-lifted pads on the power supply board. I scraped off some of the coating...

Thanks for that! I found that out a couple days ago after trying to adjust it per the manual. Noticed they were switched around and found a thread with an updated page which I printed. Little off topic, but got the hernia surgery. Feels like a perpetual nut shot. Hahaha. Probably going to get...

Thanks for the help markthefixer! I will take a look at possibly replacing that rectifier. Wound up going with the Cornell Dubilier SLP 598-SLP103M063H9P3 for the main filter cap replacement. Did a lot more digging and turned up additional results. Updated BOM has been posted. Pretty confident...

Is he part of the resistance? Ω

Cheap? No. Inexpensive? Yes! (Marketing, haha!) That said, the only inexpensive things I go for are periphery items. Cabling (monoprice speaker wire quite good actually) antennas, things like that. You generally get what you pay for and I have come to the conclusion of "Buy once, cry once"...

First round of caps have come in, more on the way. Going to order the transistors too. I still need some help figuring out the few caps that I cannot source so I can make this a one timer. Don't want to have to take apart and reassemble any more than I have to. Should be a fun project and a...

As far as replacing the ELNA CE-W 50v 6800μF 85C main filter caps goes I have been doing some looking. If I wanted to stay at 6800μF it seems that either of these two may be a good choice: Vishay 256 PMG-SI: 594-MAL225631682E3 Cornell Dubilier 381LX: 5985-85B-80V6800 Digging deeper into the...

That is the first thing I did. Thank you for the reminder! I am not taking any chances.

I have decided I am going to take on the restoration of my recently acquired Pioneer SX-737. This unit does not appear to have seen much use at all and I even have the original packing and box. Almost like it came out of a time capsule. :jump: Pictures: https://imgur.com/a/2yCpNWV The unit is...

Here's your newest FNG from Ohio. A welder who likes spinning vinyl and the high quality of the past. Getting ready to do a recap on a Pioneer SX-737 that (believe it or not) was hardly used and has it's original box and packing. Found that search results on information kept pointing me back...
