    Those would be especially interesting to me, as I've been kind of desperately seeking into on the Pioneer direct drive TTs, before getting too far into my PL-L1 restoration/refurbishment. The Video Laserdisc one might help me get my back-up/spare parts LD-X1 units running.

    But ALL of these are GREAT; keep 'em coming! They'll go into the "reference library" here. :yes: :thmbsp:

    Here is the article on the Quartz DD TT using the PL-570 as an example broken into 4 parts.
    I don't have the supplement on Video Laserdisc equipment. I am working from memory that I saw it, so take it with a grain of salt. TF 6 has an article on Laser Vision (laserdiscs) and TF 7 has an article on the CD. I didn't realise Laser Vision was an analog recording.

    Here are the articles from the memo section of TF2 & TF3. From TF2, white noise and pink noise and from TF3, loudness and frequency threshold of the human ear. The latter makes me go hmmm, when I hear people state that you can't hear a difference in a less than 3db change in volume.

    Here are the articles from the Q&A section of TF2 and TF3. From TF2, a gentleman was wondering how he blew some drivers with a 80WPC amp and speakers that would take 100WPC. From TF3, a gentleman wondering why he didn't hear a difference in volume when he switched from a SX-1010 & CS-99As to SPEC-1 & 2 with HPM-150s.

    I saw the title of this thread and thought, "Must be a short publication. How much service can you really perform on a damned tuning fork?" :D

    Great stuff, I'm going to check out some of this when I can get to it.

    Mostly taken from the PL-550_ART-188-0 service-manual which you'll find in whole in the AK Pioneer Database. That scan I made in full color to better visualize the motor-drive theories.

    Thanks to Carve it for forking-out all these scans, so to speak :thmbsp:

    Best,

    Just goes to show, there are no bounds to the knowledge here.

    Nice stuff. Most of it above my head, but I'm enjoying it.

    Thanks.

    Here is an article from the "One-Point Servicing Techniques" section called "Amp I" Countermeasures. It deals with causes and remedies for RF interference and external noise. One of the solutions involves the Pioneer JC-200 wire.

    Here is an article from the Electricity: Basic Theories section of TF 3. It is called "Electric Power and Alternating Current". It is pretty basic but it follows the Ohm's Law articles and is used to build on in future articles.

    This is an article from TF 4 called "Non-Switching Amplifiers". This would be for the SX-3900 and SA-9800 era integrateds and receivers.
