Got another Linda today. Beautiful condition. Nary a scratch on the face. Seller said she is blowing fuses. Has 3 service tags on it. Last one dated 10/4/89. I'll have to find out how she comes up on the variac and dbt. Interior and exterior is very clean. Well cared for if nothing else.

Was daydreaming about another project. Found asking prices have more than doubled and dead units seem to be nonexistent. What is everyone else experiencing?

Given a choice between a PL 4000 series II and a carver 4000t, which would you prefer and why?

What would be a good tester for a hobbyist?

Recently worked on my RG-1 upgrading caps and transistors, deep cleaning etc... Had purchased a resto kit off ebay (first apparent mistake). All the original transistors are NLA so substitutes were supplied as follows; KSC1845 for 2SC1312 KSC945 for 2SC945 No substitute was supplied for the...

Going through a fleece bay parts kit for a Pioneer RG-1 and I'm finding some questions. Can anyone tell me if I can use this cap? It appears to me to be a 1uf 63v film cap (not sure what M stands for). The parts list calls for an electrolytic. What raises the question is that the schematic...

Once again my google fu is lacking. I picked up a used BK precision 4011A function generator that was in "good working condition." The DC offset and the output level pots are AFU and need to be replaced. I seem to be unable to locate a repair manual. Can anyone help me with a copy of the service...

Anybody have a dead PD-TM1, 2, or 3? Mine has a broken loading lever. Private message me if you might be able to help. This particular part is subject to breakage on these machines. Chances are if the cartridge won't eject, this is why. Prime opportunity for someone with a 3D printer.

Need the capstan motor control board. The runs on mine lifted and broke when I was replacing the 2SC1368 power transistor. I'd buy the whole motor and board if you have it good or bad.

What if all you had was a pl400 transformer. Could build a complete WOPL 400?

Seems an o scope is somewhat needed for this hobbie. What would be a good used scope for a hobbyist? I've used them so there wouldn't be a learning curve involved. And maybe an audio signal generator too...

I am building a passive subwoofer with separate left and right drivers. They will be driven by a PL-400 that is fed by a Rolls active sub crossover. The drivers are 4 ohm impedance. I know that can be problematic for the 400 at hi output levels. I'm using this in a home system and unlikely to be...

Troubleshooting a capstan motor problem. Need a schematic for the motor control board. The service manual doesn't show it.

Looking to optimize my connection of my eq into my system. Years ago I had the SG-9500 connected between the pre-out and main-in of my SA-9800. Now I read that was wrong, should've been connected to a tape loop. It seems that the answer could best be answered if I could find what the max output...

Anybody experimented with modding existing crossovers to charge coupled and is it a significant improvement?

Picked these up acouple months back. Kept me busy when I was waiting on parts for my WOPL build.

This is my next project, "Linda". I'm convinced some people should not be allowed to touch a soldering iron...

This is Val. She's a little worn and tired, but worthy of restoration and improvement. My hope is to chronicle my first ever rebuild of this amplifier. Yes it's ambitious, but I'm retiring toward the end of this year and I want a hobby that will put 27 years of avionics skills to work. :-) I...

Greetings all, long time lurker here. Been schooling myself on the wonderful mods and upgrades these amps get, but I haven't come across a mod to install a proper power switch. Is it even an option? How do y'all power up/down?
