You can bridge the Phase Linear amplifiers, but you have to do it correctly. The 700B Owner's Manual says to never connect the outputs together! There was an undated Service Bulletin describing the technique for correctly "Bridging" the 400, 400 II, 700, 700B, and 700 II into 8 Ohms or greater...

Clipping the Model ONE. I knew if anybody could do it, it would be Lee.

Good catch, I did not see the Cylon meters in that picture. Still a bit slow down here in Florida...

Regarding the Capacitor hold down plate. I recommend you flip it over so the notch is closer to the top of the amplifier. I had to do this on mine in order for the Meter stud to clear the hold down plate. Depending on your Meter manufacturer, it may clear regardless, but that is what the notch...

A very rare unit indeed. Phase Linear 7000 Cassette Deck. Same as a Pioneer CT-A1 and introduced after Pioneer took over in 1980. Made for three years in Japan.

If I was you... I would upgrade the PL400 first. It is a much simpler amplifier and the upgrade is less costly. You will learn so much and this learning will assist you if you decide to upgrade the PL700 amplifier. The sound of those upgraded PL400 amplifiers is magical. You will not regret...

The later PL400 amps had 8 Fins, started in 1975, I believe. The last Series I PL400 was assembled sometime in 1978.

Does the "D" in DTS mean Delco?

I recently had a customer that wanted some upgrades to his PL400. He shared this Receipt/Invoice for service from Dean dated May 23, 2004 for another PL400 he still has. And it had the same problem, but now upgraded with WOA Control Board, WOA Capacitor Kit, New Output Transistors, and a few...

Avoid electrolytic caps when a Polypropylene or other high quality film cap can be found to fit with the same specs. The PL2000S2 BOM is good, but I sourced my PL2000 parts from Mouser.

The DBT identifies high current loads (shorts) in the Primary Power and to a lesser extent, downstream. Crossing output wires shows the amplifier an impedance of 0 Ohms and the amplifier will generate all the available Power across that short circuit - damage ensues. Many times the damage cannot...

George, what is the sensitivity of the Phono input in your preamplifier?

It is a moving target to try and keep up with all the wire revisions. When you get to "Z" will the next revision be "AA"?

Eric, I received my S/N stickers. I assume you have too. Should we agree on a location for the stickers, just to be consistent? Maybe Joe has some input. He likely already attached his stickers to S/N 1 and S/N 2.

Can you send me a copy of the Rev V Wire List. I like all the reasons you mentioned.

SS hardware is so sexy in this amplifier...

You inspired me to pick up where I left off last week.

Good man. I never thought to twist the Switch Tabs...

I want that cookie cutout set!

If there are no pictures, it didn't happen... Also, can we see a picture of the Cabbage Case? Please?
