    Replacement for obsolete Q1 and Q2 transistors?

    That's a good question I've meant to ask as they use the TIS97 or the GES97 in the preamps also. I researched this a couple years back and never found a suitable sub. The guys who rebuild Mini-Moogs reportably demand original TIS97 from what I read. There are also pinout variants of these...

    phase linear 400

    Original 400 S2 pot and wiring. The middle lug (red wire) is known as the "wiper", and ALWAYS carries signal to the control board. The black wire carries signal from the RCA to the pot. The sliver wire is the ground or shield wire. Goes from the RCA copper plate to that pot lug, then from the...

    Phase Linear 400 bias, advice

    Are the RCA jacks shorted to chassis ground? The jacks, input and output, must be insulated from chassis ground. The RCA's should have fiber insulating washers on both sides of the chassis hole. The RCA's ground to the copper plate, with it's attached soldered on, ground wire.

    Gene, what transformer are you going to use? That weird dual primary one with the all black wiring?

    what are you listening to?

    Yeah, but it's weird. How's it make any money? Lots of great old top 40 tunes, Joe Cocker, Beatles, Carpenters, Heart, etc. Very little DJ interruptions, in Spanish. Can't say I've ever heard a sales ad. Granted I don't understand the DJ, because of the language, but how do they make $ to...

    THE Crossover Thread
