Does any one have a Caps list for the 1000A ?
HEY GREAT WORK, i have a sansui 1000a and i need to recap and setup it with original values.
Could you give me photos or wiring diagram and example where i should read and measure current and voltage values, and the resistor or cap i have to change and what type?
I know the output tubes have to be set for a bias current but i don´t know where i need to read, i know how to measure this values, volt, amp (mA or uA, etc.) but not where and how.
Could you make a complete step by step repair guide with photos and wiring indications?
Hi, i´m starting to restore my sansui 1000a but i need to know what kind of cap are this and what type i have to buy for replacement:
SUZUKI MP-R
SUZUKI MP-H
SUZUKI CPTNN-D ECN-U
ELNA OIL JPC-A
I hope all answer that you can send please
Need some help identifying witch model 1000A this is pleasSerial # (if it's still there) will be either a stencil # between the AM antenna and the one output transformer, or a stencil or tag near the center back between the output and the power transformer.
About 1970 the capacitor industry changed the values. The 200uf 25WV 40 SV cap works out to 200 microfarad 25 "WORKING VOLTS", 40 "SURGE VOLTS". The replacement cap would be a 220uf/25V,35v, or 50v. The caps with a + going to ground aren't actually showing the positive side gong to ground. It was actually a shielding setup. The + equates to the outside layer hookup, which is the shielded side. It's more than likely a SUZUKI PIO. This is a BIPOLAR (non polarized) cap. You can use Vit Q, Orange Drops, Illinois caps, or any other bipolar cap as long as the values are within spec.
The separate resistor is R127. It's mismarked on the schematic as R179. See pic attached.
As for what capacitors to use, that is up to you, but Orange drops and Cornell Dublier, and Mallory are good standard replacements. The Orange Drops can get quite large in some places (the .33/600V coupling caps at the outputs come to mind) and you may or may not want to squeeze them in. As there isn't a lot of room Sprague caps aren't really recommended for size.
I used Orange Drops(715's) and CD DME series caps. I don't subscribe to the 716's sounding better because of the copper leads. They sound the same to me.

Awesome I will definitely start a journal thanks for the infoJason; Judging from the big white power resistor laying on it's side, the later style Sansui ID Plate on the Power transformer, & 4 bias pots, it's a LATE Edition (probably '69 to '71). This would be the last iteration of 4 bias pot model before production stopped. AND it looks like it's still Virgin underneath.
I WOULD recommend if you DO rehab this unit, to start your own thread so any and all questions you ask are answered directly pertaining to your unit. It gets really confusing when 5 guys have the same unit,asking questions, and 15 guys are answering questions.
