FYI #12: Tone Arms for the PLC-590

Pioneer offered two tone arms for the PLC-590 turntable: the PA-1000 (carbon fiber) and later offered the PA-5000 (aluminum).

Doc
 
The difference between the DT-500 and the DT-510 is primarily that the CT-500 is Blue Fluoroscan display, while the DT-510 is a blue LED display. I could have that backwards, but I think I have it right. I have one of each, and I can check when I get home, if anyone thinks its important.

As a side note: the DT-510 shows a bit of cost reduction that was common at that particular time in audio history. Still a nice unit though.

FYI #14: Fluroscan® meters

Fluroscan® meters began on Pioneer’s Amps, Cassettes, and Reel-to-Reels in 1979, but not on Receivers until 1980.

I've got one each of the DT-500 and DT-510, but immediately added them to systems as I got them, and never compared them side-to-side. I need to do that next time I move components around.
 
I had a 500, 510, and 550. Sometimes, the clock would just go bad. Not sure why. Thought it might be related to the voltage selector being incorrectly set on the back.

Anyway, I got rid of the 510 and 550, and now have 3 of the 500s. 2 in use, 1 as a spare.

Pioneer’s best tuners, in terms of Image Rejection or Image Response Ratio, are the F-26, F-28, SX-1980, TX-9500 II, and the TX-9800, selected from tuners and receivers that were available from 1970 to 1985.

F-26 Tuner was so expensive, that not much been sold :no:

Sorry Doc, but as I think to know, first Fluroscan Pioneer was CT-F900 build in 1978 :scratch2:
 
Yes, some of those components were not manufactured on a strict "model year" basis. We tend to think of something only being available from January to December of a year, when the actual manufacturing cycle was different.

Kind of like buying a 2007 car in September of 2006.

FYI #15: HPM-100 and HPM-900 Speaker Grills

HPM-100 and HPM-900 have the same size speaker grills. If you are missing a grill, this can help with your replacement. Just keep in mind that the attachment pins are different diameters.

Doc
 
HPM-100, HPM-100M, HPM-110, HPM-110X have the same size, but different surface. HPM-100 wood - HPM-110 Matt Black
HPM-100 could handle 100 Watts,
HPM-100M and HPM-110 200 Watts.
HPM-110X ferequency response started at 50Hz instead of 30Hz all others :yes:

On the scan you can see HPM-110 and HPM-900 have the same dimension.

FYI #16: Series 20 head shell

The Series20 PLC-590 turntable, with the PA-1000 tone arm, had its own head shell: The PP-312, also made from carbon-fiber material.

FYI #18: Pioneer's P-D1 CD Player

The P-D1 was Pioneer’s first commercially available CD player, and sold only in Europe and Japan, in 1982 -1984, and was Pioneer’s own design (not Hitachi, Kyocera, Sony, or Philips).

Thanks to Axel for his analysis and comparisons.
