Translation: I am looking for a 400 phase linear VOLUME METER to buy as mine is broken, if you have one for sale let me know thank you

Don, I received them yesterday and installed one today. They are an exact fit (We Have A Winner!). Thank you for searching your parts bin. I you need something from me - it is yours. Sincerely, Mark

RCA 410 Driver Transistors are the consensus here for ruggedness and stability in the Phase Linear Power Amplifier driver position. They are slow, so oscillation is not an issue. The role of the RCA 410 is to set up the bias and drive parameters for the Output Transistors that actually do the...

Well, it could be worse. You could also be addicted to Harley's and Bourbon... nevermind.

Retirement is looming later this year. No doubt that will free up some time to catch up. Ha! When you retire, you are working for a new boss, and that guy is a pain in the ass.

Est il à vendre = Is it for sale.

Thanks 007, The ebay post did not give any dimensions or the hole spacing (I need 1 1/8"), so I went ahead and ordered one for $20.00. I should know in a few days. I don't think the PL700 Kulka original AC Receptacle was UL listed, but that is an added bonus.

Don, the manual you posted is the later version from February 1981. It is a pretty conventional pdf digitized scan of the original document. I think the original June 1976 version of the PL700/PL700B Service Manual might have a slightly better scan of the PL0171 control board. I posted it here.

I keep looking for one of those large metered Variacs and every time they say, "WOPL Sniffer just bought our last one."

You are in dangerous original/unmodified equipment territory. The board and the amplifier are very clean, but are all original and likely 45 years old. At a minimum, you should add a DC Protection Relay/Delay Board to protect your speakers. It is cheap insurance. You can install it yourself if...

Your soldering skill on this ancient printed circuit board is nothing short of amazing. I have an original unmolested Phase Linear 14B Board. Comparing them with the above pictures shows no irregularities. This one has pairs of GES 97, and GES 93/MPS 93. You can have this P14B Board if you want...

Might work. The #6 screw hole spacing is the critical issue at 1.125" or 1 1/8" center-to-center. Yours has slots, so it may be a winner. I can file off that Pioneer logo, but it is comical because Pioneer bought Phase Linear... I will send you a PM.

My understanding (Joe may confirm) that Dickey joined the band at 17. Probably the youngest guitar player to perform on the road.

Amps like that were responsible for Joe's replacement Control Board.

It is an American company founded in the 1939 by Eugene Kulka. I believe they are still in business selling electric light fixture components and Mil-Spec terminal blocks. The non-polarized AC Jacks are probably illegal to sell today. That's why they are obsolete.

I am looking for an AC Accessory Jack for a customer's PL700 (the original amplifier, not the PL700B nor the PL700 Series II), Phase Linear changed to a different AC Jack after the PL700 and the hole spacing is different in the later amplifiers. These fragile Jacks were made by Kulka (P/N 221)...

The room is somewhat narrow at 12 feet, but it is deep at 30 feet. I stand in the back and smile a lot. The WOA Mode ONE is my daily listener since February 6th and I have not had a single issue with it.

Actual speakers, of course. According to the Owner's Manual, the recommended power for the Carver "Amazing" line array speakers is 1200 Watts at 8 Ohms. I am almost there...

Here is the updated Rev G Meter Board for the White Oak 1000 (front and back). The layout is a little different, but the real improvement is onboard voltage regulation to keep the Meter LEDs at the same brightness regardless of the power supply sag during heavy demands. The Rev G also features...

"Look at the size of that thing!" And yes, size does matter. I think I could get a 10 Gauge AC Power Wire into that blue connector. Note also that the Lower Right Mounting Hole is plated for Grounding via a 1.5uF/200V Panasonic Film Capacitor. Joe added a second LED to confirm relay operation...
