Is it likely that these output devices will get hot? If so, the isolated tab devices may not be able to conduct heat away from the device as well as the metal tab devices you specified.

I know that place. And I used to get the best submarine sandwiches right down the street at Surf Side Deli, in the corner by Regatta Men's Wear. I actually had a consultant client out on Point Loma on Woodward Road. It was the Navy Training data center for Undersea Warfare. The whole building...

I'm waiting for the paint...

I joined the Navy while still in High School. There were 11 kids, so I knew my chances of parents paying my college tuition was a fantasy. I scored 98 on the ASVAB and they wanted me to be a Nuc (Nuclear Power Program). I said no way and accepted Advanced Electronics and Sonar School. My first...

Heaven...

That's funny, because when I see a vintage Altec or JBL crossover for $500.00 - I cry. They are that good and I want them. It is not the parts really, it is the engineering that went into the design. I use a pair of JBL 3110 800 Hz crossovers between the JBL K120 woofers and the 2426J...

Yes, the Model ONE is weight balanced in the center, unlike the exposed transformer Phase Linear amplifiers.

He lives out on Cape Cod and has an elevator in his house. My brother is an elevator mechanic, licensed in Mass. He did some work on the elevator and also an inspection/certification for free. Mr. Taylor was so impressed, he asked my brother if he wanted to see the "Guitar Room". It was also his...

The 400 Watt Dummy Load that I connected to one channel of the Model ONE got too hot to touch after just a few seconds. It also blew the 10 Amp Fuse in the Model ONE (Joe said that it was because I fed it a 1 kHz sine wave), a 1 Volt continuous wave into the Model ONE would likely draw 25 Amps...

Bring David Janszen into the Forum Perry. He is a good guy to have around here.

Full WOPL upgraded amplifiers and the great Model ONE are "Dark" amplifiers. With power on, all cables connected, volume down, and close to the speakers - there is nothing there. No hum, no hiss, no buzz, no crackle, no pop, nothing. Does not matter if you just turned the amplifier on or it has...

Are you kidding me right now? Lee, you are too close to Canada. The stock PL Binding Post Nuts are 7/16". Phase Linear didn't use any Metric crud in their amplifiers. Besides, I can't find my 10mm socket right now...

And gold-plated too!

Good to know, my Leader LSG-231 manual says it outputs a composite signal of L-R, L+R, L, and R at 1 kHz. I wish I had a spectrum analyzer. But then there would be a whole new steep learning curve. I just downloaded and printed the Service Manual. Time for some studious reading.

Right! I have a Leader LSG-231 FM Stereo Signal Generator and I am not sure if it needs any attention prior to attempting a tuner alignment. My oscilloscope is a Tektronix 2235 (100 MHz) and i think it is up to the task.

And, they are only $3.81 each. I believe these excellent Bourns Potentiometers have the round shaft. So if your PL700 II has the newer knobs for the flattened shaft, you will have to file a "D" shape into the shaft. The cut along the shaft should be 0.250" (1/4") long and 0.090" (3/32") deep...

What upgrades/servicing are you doing to the Carver TX-11? I have a TX-11a and I believe it is unmolested. I was planning to recap and align the tuning section someday. Right now my go-to tuner is a Phase Linear 5000. It likely needs some alignment as well.

In the above schematic, C2, the 470nF (.47uF) capacitor is not a low pass filter. It is a DC blocking capacitor, in circuit when the DC/Normal Switch is set to Normal and blocking frequencies below 40Hz. The DC/Normal Switch bypasses C2 for Inputs down to DC. The low pass filter is located on...

Let me add a few points here. Yes, a well behaved Phase Linear Series II amplifier is a thing of joy. And if it only has a few issues, spending $5 and a few hours of your time may provide many more years of use. However, let us see what a (generic) $350.00 WOPL upgrade can give you: 1. The...

Are these the Phase linear 700B or 700 Series II amplifiers? The shop likely charges $80.00-$100..00 per hour labor. Many technicians on this Forum will charge less. Just food for thought. And, four months to wait for a diagnostic is ridiculous. You mentioned the amplifiers are being serviced...
