    PL 400 series 1

    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...

    Barn Find PL400

    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...

    I Need a Part

    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.

    "Ramblin' Man" Has Passed at 80 Years Old

    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.

    I Need a Part

    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 Need a Part

    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)...

    White Oak Audio Design - Model ONE 1000 Watt Stereo Amplifier

    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.

    White Oak Audio Design - Model ONE 1000 Watt Stereo Amplifier

    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...

    White Oak Audio Design - Model ONE 1000 Watt Stereo Amplifier

    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...

    White Oak Audio Design - Model ONE 1000 Watt Stereo Amplifier

    "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...

    Help with transistor substitution on PL400

    It is OK to dip your toes in with the upgrade of a PL14b control board, many of us have done that. But when you pick up a White Oak Audio "Dual Mono" Rev G1 Control Board with four precision, +/- 15V regulated power supplies onboard, through-hole plating and two-side heavy copper etching with...

    Barn Find PL400

    Many of us started out with tubes. Mine was a McIntosh 225. Eventually, tubes became expensive and then very hard to find. It has become better lately, but for me the damage was done. I migrated to a Marantz 2285 and never looked back. Now, no more foreign amplifiers for me - I just stick to...

    700B WOPL Candidate

    The handles and meters are worth the asking price.
