PU01 out of the way already. It's all downhill from here! Great looking unit. keep us updated.
The loudness button definitely boosts the bass on mine. Not sure what’s going on there. Maybe more Deoxit of switch?

Congratulations and great job! What are your speakers? It definitely makes a difference with my KHorns and I use it a lot.
....then I'm going to pull the PU01 board again and double check everything.
Haha! It's not that bad actually, especially with the tone board have a connector!
Hello Guys!
I've made an online BOM of all components mentioned in this thread (as I understand, this list is largely inspired by Leestero's thread on the 2325 restoration), with links to the specific Mouser product pages. I hope it's okay I share this link here. I have not modified any part, some items are currently out of stock, but you should be able to find suitable replacements.
I make this list for myself as I'm planning on doing this restoration as soon as I get all the parts, and I thought it would be nice to share it with others stumbling on this excellent thread. Thanks Steven Tate, and Leestereo!
So here's the link: https://docs.google.com/spreadsheets/d/1JaAcbN-dXUsYx6ALQSoBtqMAwV9E9TQXRI0nVWu_42I/edit?usp=sharing
I'm new to the forums, so if sharing this might be a problem, please remove this post! If anyone wants to edit the list, shoot me a pm or something, and I can send you an editable version or something?
Recapping my P700 board and found this 27k resistor with outer layer peeling(see pictures). I would like to ask members of this forum for advice to make sure I am ordering the correct part. Thank you.
I am sorry. I don’t understand what you mean.Blown output transistor somewhere on one of the amps. Unplug the power connector (power off), one at a time and turn it on to see if that's it.
There is a white connector that powers the amp board. He was suggesting you disconnect that connector and power up the receiver. If the relay works, you know the problem is on the amp board or an output transistor.I am sorry. I don’t understand what you mean.
I found out the amp on right side have this problem
Did you mean. Disconnected this white wire right?There is a white connector that powers the amp board. He was suggesting you disconnect that connector and power up the receiver. If the relay works, you know the problem is on the amp board or an output transistor.
yes. It is already out and relay click.If the amp is already out, the plug is disconnected. It connects to those four vertical pins just above your circles. With that amp out, does your relay click?
P600 Dolby Circuit Board
This one is a veritable pleasure to work on because the whole board comes out and you can work on it on the bench. Lots of 10uF caps on this one just like the tuners. Here is the board after replacing all electrolytic caps - nothing else - and the parts list. Had a shipping issue with the parts I'm waiting on. It's been five days since I ordered from Mouser, and they usually get here in two days. The Mouser warehouse is about 10 miles from here. After five days, no parts, so I checked the USPS tracking. The parts went from Mansfield (10 miles from me) to Ft. Worth (about the same) and then to Amarillo (300 miles away!) then finally back to Ft. Worth where they are now. I will probably get them tomorrow. The system obviously hiccuped on my parts.
