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)...

I have a customer's PL700B with a real head scratcher. I am looking to the group to help me figure this one out. I thought I had seen everything. I don't know if the amplifier ever worked previously. It already had WOA Capacitors and a WOA Blue Meter Illumination LED Board installed. I replaced...

I am suddenly attracted to a gently used CD Player. My understanding is the now-defunct OPPO company made some good ones. I don't need video, just audio outputs. Is there a recommendation or a consensus out there for the one to look for? I was thinking BDP-105, but I am open to those with other...

Are there any Gmail technicians out there??? I created a .biz account in Gmail just for fun. When I saw the monthly cost $21.60), I decided not to go forward with their "Recommended Plan" but there is no exit from that Google Workspace Accounts page. This one...

This is a picture of my bench "Mule" Full Complementary PL400 "WOPL" amplifier which I use to test newly assembled WOA Rev G1 Control Boards for customers. Yes, the wiring is long because I need to drop the Faceplate twice per test and sometimes I test two or three boards in one session. Also...

I have a Carver SD/A-490t CD Player circa 1991. It will play a CD flawlessly but chokes on a CD-R or CD-RW. Can this be corrected with a new transport or is this a design limitation?

I am pleased to announce that I have purchased a new amplifier kit from White Oak Audio Design, the Model ONE. While there are some recognizable features, such as the PL700 Backplane Boards and Heat Sink Fins; this is a completely new design, engineered by Joe King (Gepetto). He can provide more...

I need a Harley Davidson part and there is only one in the USA. It is P/N 17011-01KB (a gasket set) and it is at Tim Surdyke Gold Star Harley Davidson, 2435 US-67 Festus, Missouri. They have some crazy policy of not selling anything to anyone outside their "Dealer Territory" which is a 30 mile...

I would like to learn the consensus of the WOPL Upgraders. Do you remove the red plastic film from the LED Meter Lenses, or leave it in place? With no brightness control for the LED Bar Segments, would it be too bright? I should probably try it on one channel and see what the difference would...

Hello, I am looking for a Phase Linear-knowledgeable technician to help a long-time PL customer. His name is Steve T. and he lives in Oak Harbor, WA. Steve has a PL400 that has received new parts, installed by a local repairer, and the amplifier will not come to life. His local repairer is...

Anybody have a pair of the square silver buttons as used in the PL400 or PL700 Series II amplifiers for the Power or Display switches.? I have a customer's amp that is missing them. I will pay profusely and promptly. Maybe a source for a look alike?

Who knew that the PL700B and the PL400 (eight-fin) transistor covers were not interchangeable? I always assumed the width was the same until I tried to put a PL400 transistor cover on a PL700B, it will not fit. I suppose a PL700B transistor cover would fit on a PL400, though. Oh, and by the...

I have a customer with a PL8000 turntable that works but will not lift the arm by itself. Anyone interested in helping this guy out with his turntable?

All these years and I never noticed the difference in the PL700B faceplates. Is yours a righty or a lefty? Hint - look at the meter sensitivity switch labels... (I hope there is not a thread on this, I would feel dumb) When did they make this change, and why? Calling Ed Blackwell. Hey Ed...

From the website: For 28 years 17 Phase Linear 400 stereo power amplifiers drove the 5 speaker arrays. Together with the 4-way electronic crossover networks, they could produce the same sound level as a single 20,000 watt amplifier. Dick modified these amplifiers for improved frequency...

Anybody have an extra set of Top and Bottom covers for a PL400? I have a customer that needs a set. He bought a PL400 on ebay and it arrived with no covers...

Here is a picture of a factory fully complementary PL400 from a customer in Australia. It appears to be made in 1983, the last year of the Phase Linear name before they became purely automotive components. This was during the time they were owned by Jensen, which began in 1982. I am assuming...

During a routine customer WOPL upgrade on a PL400, I noticed two of the Nylon shouldered washers would not fit into the backplane of the amplifier, after I had chamfered all the holes and flattened the back and heatsinks with my calibrated flat bastard file. This is a well-documented problem and...

I found this link for WOPL Builders. I think this is a good price for Buss 10 Amp fuses, Made in the USA. I bought a box of 100 because $0.25 each is a pretty good price, I think. https://www.ebay.com/itm/231303032358?hash=item35dabc2e26:g:zq4AAOSwxH1T5PcN

I am posting this picture of a Customer's PL400 Series II (with his permission). I am quite proud of myself for this work. He said no holes in the chassis, but would allow one for a chassis (Earth) ground. I expanded it slightly and installed a 12 Amp miniature Raytheon switch, from the Space...
