    Hoo boy.

    That certainly is a good question. I'll chalk it up to my insanity.

    Hoo boy.

    Yeah, it's connected. Every test I've run so far shows everything to be in proper spec. Just this issue of the DBT when speakers are connected.. Drives me nuts. I want to dial that before I install a WOPL setup. Kinda want to know if I have a backplane or PCB issue, or both LOL

    Hoo boy.

    I picked up a pretty nice PL400 and ran it through it's paces with a DBT and variac. It had a missing right supply fuse, I put one in. Everything tested fine. I was able to adjust the bias down from 450mv to 360mv, and the DC offset was close to nil. However when I hooked up speakers, the DBT...

    phase linear 400

    I had this issue once. Leaving the dbt connected, I took the variac out of the system and powered up. Everything was groovy after that.

    Phase Linear P3600 preamp

    The P3600 arrived this morning. It was the best packing job I've ever seen. A heavy duty box containing the original Phase Linear box. Advertised as "Open box new unit", I was skeptical until I opened the box. To my amazement, there it was, just as it was packed in 1982. If it were a baseball...

    Phase Linear P3600 preamp

    Thanks bud. The voltmeter was like $11 on ebay. :) So far so good with the Yihua desolder gun. I found the trick is to let it heat up real well and draw the old solder in while poking it with a supplied wire. After that, it seems to be OK. I haven't used the Hako, but I hear they are great.

    Phase Linear P3600 preamp

    Opps, I did it again. I purchased a new in the box P3600 preamp. Waiting for it to arrive/survive shipping. There really aren't many threads on the internet regarding this preamp, but the ones that exist seem to like it. Any observations from the peanut gallery? I'll be able to compare it to the...

    phase linear 400

    Was a thought, but nah, I forgot what it was.. lol. I run a cheap set of Memorex speakers for raw testing, then up to some Neumi's, and then over to the living room and the JBL L7's, or AR LST's. I did have a blown resistor in one of the L7 crossover tweeter circuits, but it just kept signal...
