    Thanks Lee, I'll poke around through the various threads. I am only interested in full comp data.

    Does any body have test data using the latest WOPL control board and the original PL output circuitry vs WOPL control board w/ backplane boards?
  3. Lee, What is the consensus on the new x-overs?...

    Lee,
    What is the consensus on the new x-overs? Sound, power handling, etc?

    I would say there is nothing to gain from using resistors with non-magnetic leads or end-caps.

    Just a hand grenade audio-phools throw out there to make the water more muddy.

    Hi Ed,

    - S/N spec is weighted, but I can certainly do un-weighted.

    - The power bandwidth would be -3dB at rated power for the 700. For the 400, the power bandwidth would be a bit better due...

    IHF-202 Audio Amp Specification

    This should help with the write up on amp test procedures.

    I apologize for the "crooked scan". It is a copy of a copy.

    Thanks Glen for confirming that.

    I tried to keep the PLX the same size as the original PL36, but there were just too many components in the new design to use the same size PCB and have room to...

    The new PLX driver board is slightly larger than the original PL36. The PLX is 8.25" x 5.75". The original Pl36 is about 6 3/4" x 5 5/8".

    The PLX will fit into 400 and 700 chassis, but I'll have...

    After tossing the new amp idea around for awhile and considering the 400 and 700 chassis layout, I have finalized the amp design. It's not the one I was anticipating originally, but it is a good...

    I have long suspected that the bias circuit on the 400 / 500 / 700 was too sensitive. A small change to the bias circuit confirmed this. See revised schematic for changes.

    Adding RNew (27 Ohms)...

    Audio Control used the 4136 extensively in their early car audio products in the mid 80's and after. Their products were not what I would call "inexpensive", but they did develop a cult following...

    The sound improvement will probably not be as incredible as you might think. Certainly not worth $5. If 100 people answered your question, you would get 100 different answers.

    This is a full comp amp, so it uses MJ15024 and MJ15025's. A quasi comp would use all MJ15024's. I have a lot of these MJ150xx types and I don't run my amps hard so they are fine for me. The MJ21xxx...
