    Phase Linear 1000 AUTOCORRELATOR

    If you mean the SAE 5000A, yes I have one for sale because I no longer have a turntable nor a tape machine of any type. It has been upgraded with new Electrolytic Capacitors and performed well when I had my turntable, it includes the Manual in soft copy. I will send you a PM. PM sent. Now I...

    A Shot in The Dark

    That is very kind, but I am hesitant to start a "GoFundMe" for this guy. This Forum is so great that I feel others might be compelled to help out and I am not that good at running a cash ledger. Hell, I might get more than he needs. Thanks for the offer, you guys are amazing!

    Yes, Joe is sourcing them. They will likely be similar to or the same as the WOA Model ONE VU Meters because the new meters require a new Meter Bracket, Meter PCBs, and Faceplate to fit the PL400.

    Passive Horizontal Bi-Amping question

    And in the WOA Model ONE clipping occurs around an input signal of 2V?

    A Shot in The Dark

    Thank you for the offer (a good one). But I have bitten off a bigger piece and told Joe that I will be his Guinea Pig for the initial test of the WOA PL400 Meter/Faceplate Upgrade. He is working on the fabrication part right now and I may see the parts arrive before the end of the year. This is...

    Phase 400-II Quasi comp to comp conversion

    You will also need the two PNP columns of ONSEMI MJ21195G Output Transistors for the Fully Complementary operation to be... complementary. Personally, I would change out the existing NPN Output Transistors as well, use ONSEMI MJ21196G. If your amplifier still has the Silicone grease/mica...

    Serious input wiring cables!

    Black Sabbath is back. One Last Time...

    Ontario Motor Speedway was a great outdoor venue and Tycobrahe Sound did an outstanding job with the sound system including use of the Eventide Clockwork 859-second digital time delay between the front and rear speaker arrays. "54,000 watts of audio power... 105 dB SPL at one mile... 200,000...

    Birth of a New Model One

    The way that the Output Transistors in the Left and Right channels are on opposite sides of the amplifier gives us that stereo separation even in mono recordings... 1956 was a good year!

    Black Sabbath is back. One Last Time...

    I saw Black Sabbath play at the California Jam on April 6, 1974. Tony's guitar sounded like 1000 chainsaws on overdrive but the music was so clear, I can still remember the band playing together like a well-oiled machine under Ozzy's maniacal leadership. Tony Iommi was the primary composer and...

    The Bias reading will probably not change much, now that you have two rows of Output Transistors installed. The real Bias check is after all your Output Transistors have been installed and the amplifier has been producing some serious music for thirty minutes or so - it will be nice and warm. Or...

    I install the thin Nylon washers under the Control Board and under the two Retaining Nuts because I have to remove/replace the Control Board often during a rebuild. And it helps on my Bench Test Mule Amplifiers that I use to test Control Boards for customers. I should install wingnuts!

    Yes, because there is a discharge path now through the "Fused" and "Unfused" rails. However, I always measure or just install a 200 Ohm 10W bleeder resistor between both caps, just to be sure. I have seen too many sparks... You are smart to measure!

    Joe is generous with the wire lengths going from the Backplane Boards to the Control Board to make sure you have enough. You can certainly trim them so that the bottom cover does not come into contact with them. Completely optional. Measure twice, cut once! Input Jacks look great!
