    PHASE LINEAR 700 II AMP AND 3500 II PREAMP

    Their all nice. but I like the way the SX-X50 Fm tuning knob spins, you can spin it fast. The only thing I don't like is cleaning , every thing goes thought every SW and if its not clean you can get static and/or cracking noise.

    How to determine where hum is coming from

    First, does everything work except for the Bussing? I did not look at the board wiring so it could be their also I like to test just the amp first (ground loops can be a lot of things) I like to disconnect the Rca inputs and retest. than . I also like to Flip the 2-Prong AC plug and see if...

    phase linear 400

    Might want to double check , you should have 3 Emitter Resistors .33 Ohms and your R1 and R3 1 Ohm But the bottom one have different value resistors might want to check to see which ones are bad R10 1 Ohm , R21 10 Ohms and R23 150 Ohms
