    1. Late version 400C preamp -- modified to eliminate all hum originating within the unit.

    2. X-202B -- Modified only to include individual bias test points and Screen Stability resistors, otherwise stock.

    3. R-200 -- Purchased with full restoration.

    4. FM 100B -- Fully restored.

    5. Late version X-101 -- Project in waiting.

    6. 500C -- Project in waiting.

    7. X-202 -- Power supply fully rebuilt, defective components replaced.

    8. 800C -- Fully rebuilt, including individual bias adjustment controls and auto tuning meter lamp control.

    9. SA-100 Clone -- My version, including EFB(tm).

    10. 300 Multiplex Generator -- Fully calibrated.

    11. 400 Receiver -- Highly modified per thread on this forum.

    12. 590-T Console Tuner/Preamp Head -- Fully functional, powered from diy standalone power supply. Performs lab rat duty.

    Ross -- I would be particularly interested in the installation of the MPX-65 into your 202-T. I have performed such a modification on that unit, which is quite involved if the resulting unit is to work and act like a real "Fisher". In particular, the 202T offers no ability to easily select FM mono reception (for quiet listening on distant stereo stations) once the MPX-65 is installed, nor is there a way to accurately tune the FM Stereo MPX composite signal on stereo stations for most accurate MPX performance. Finally, there is no way to indicate reception of a stereo station, either.

    I resolved all of these issues with a number of modifications to the unit (in addition to the basic MPX-65 install), which included a switching relay system to facilitate FM Mono operation, and modifications to the FM tuning eye tube circuits so that it operates like that in a 400 receiver: In FM mono mode, it is a signal strength indicator reacting from the limiter stage signal as normal, only partially closing on maximum signals to facilitate tuning but also to indicate Mono operation. In FM Stereo MPX mode, it then reacts to the pilot signal from the MPX-65 for best FM Stereo performance, fully closing (or nearly so) on FM Stereo stations to in fact indicate reception of FM MPX Stereo, but remaining wide open on (and to indicate) reception of mono FM stations when FM Stereo MPX mode is selected.

    It ended up being quite a project well beyond the simple install of the MPX-65, which I think is why you see so few of the old MPX-20 designed units actually converted for MPX-65 operation. Since you indicated that yours was converted, I wondered how these areas were addressed. To my knowledge, Fisher never published any instructions for installation of an MPX-65 unit into MPX-20 designed tuner/receivers, so I wondered if you knew any of the details for how these issues were addressed in your unit. Any info appreciated!

    Fisher 400, 500B, X-101-C, and R200 tuner. The 400 and 500B are very early, the X-101-C later. Not sure about the tuner.

    3 pairs of 30A's. All rebuilt by me with different parts in each one. I do have a favorite, but they all deliver the musical goods in different flavors.

    1 pair of 20A's. Redone by the dreaded Fisher Doctor for the previous owner and now rebuilt by me. I don't hear too much about the 20's...another great EL84 amp.

    400C preamp. Rebuilt by the late Paul Gryzbek at Tube Audio Design...(formerly Bizzybee)
    It's simply a killer preamp and Dave G's changes/improvements are next on my list.

    101R tuner. Rebuilt by me. My lastest project, and quite a bit more involving than the amplifiers. It's a mono tuner that requires a MPX unit for stereo, but that's OK with radio being a low priority for me these days.

    Just for kicks, a Fisher 855 CD player! It's one of the earlier CD players from the 80's, made by Sanyo, I believe. "Laboratory Standard" of course. Still sounds pretty good and lacks that "digititis" that early digital was known for. I'll say this: it still works and my High End $1600.00 Proceed player quit on me more than a decade ago.

    TA600, partially rebuilt, need to do the can caps.
    Philharmonic chassis 290-T, all original
    MPX unit from a 500B, believe its an MPX-65. Plan is to make it a stand-alone external MPX unit, probably for the TA-600.

    400C Preamp. Dave, do you have a detailed description somewhere of what you did to eliminate hum? I need to eventually go through and redo some resistors, etc and may as well do what i can for any underlying issues.

    One lowly SA-100 I recently acquired but seriously underrated. Wow, this thing gets HOT! But one beautiful sounding piece. I never gave it a chance to warm up before. I am now very impressed with it. Can't imagine how much better Dave's mod would make it sound.
