Pioneer SX-1000TD


This is the Pioneer SX-1000TD which is one of Pioneer's first all solid state receivers. There were a couple other similar models in the SX-1000TW and SX-1000TA. I believe the TA model actually had one tube in the tuner section while the all solid state TD version was a European release and the TW was sold in the U.S. Still, it also looks like the SX-1000TD was rebadged and sold as an Allied receiver in the U.S. as well.

The SX-1000TD is a 50 watt per channel receiver and has a great lates 60's vintage look to it. It measures 15 15/16" X
13 3/4" X 5 3/8" and weighs roughly 23 pounds.

The TD and TW models look very similar on the outside. Here is the TW model in a wood case:

The TA version on the other hand looks very different:


Pioneer SX-1000TA


As I mentioned above, the TA version has a tube in the tuner section as well as two Nuvistors which are actually tubes as well so there are really 3 tubes in the tuner section. The Nuvistors were used in some RF applications during the mid 60's because transistors were still hard to produce and were less than reliable. So, the TA version of the SX-1000 is a hybrid design and was probably produced before the TD and TW versions. Once Pioneer decided to go all solid state they quit making the TA and switched to the TW and TD instead. Obviously they redesigned the front panel as well as some of the circuitry as well. I'm not sure of the output of the TA version. I've seen most quote it at 50 WPC but I've seen others claim it is 20 WPC.

Another thing you may notice about the SX-1000 series is that they have strange speaker plugs on the back panel. The TD model shown above has an adapter plugged into the main speaker outputs. The adapters look like this:

You'll need these to hook up speakers to your SX-1000 model receiver. They can usually be found on eBay.


Here is a really nice SX-1000TW in a wood case. As you can see it looks essentially identical to the TD version.

All of the Pioneer SX-1000 versions are in demand from collectors and enthusiasts. The restored TW version above sold for $335.00 which is about the top end for the SX-1000's. A decent working unit without a wood case would bring about $80-$100 while a nice unrestored unit in a wood case would bring $100-$200.

  1. I just purchased a Pioneer SX-1000TW receiver and was wondering if this model had a dial lamp. My meter and signal lamp lite up however it appears that the dial doesn’t have a lite.

  2. Hi, yes, I’ve seen pictures of the Pioneer SX-1000TW and it does have a dial lamp. I believe the bulbs are 6.3V and .25W and you can sometimes find them at radio shack or a hardware store. Just pull the old lamp out and take it with you so you can match them up.

  3. Hi, great post. My grandparents just gave me this receiver with 2 speakers. Sadly it didn’t come with the adapter plugs. Is there a way to “modernize” the terminals that the speaker wires connect to in order to take RCA or something like that? Not exactly the best with vintage electronics, but wanting to learn so I can hang on to this. Thank you in advance!

  4. The plugs can be found on eBay occasionally though they aren’t very cheap (about $20+ each). I know many have tried to make them in various ways. Probably the best idea I’ve seen, though I haven’t tried it, is to use male spade crimp terminals. They basically just plug into the plug on the back of the receiver and you crimp the speaker wire onto the other end.

    Try this link for some that are available on ebay…

    Male Spade Crimp Terminals 7.8mm

    Or just search for “Male Spade Crimp Terminals”. Some have said they are 7.8mm connectors but I haven’t tried it so I’m not sure but I would try those first. Or, you could try to measure your terminal width to see what it is. I think 7.8mm is about 5/16 inch.

  5. Just saw this site. Thanks guys. I have my father’s SX-1000TD/wood case in great shape he bought in Okinawa, Japan in 1969. No manuals, sales/repair receipts, box. When I hooked it up to my Dahlquist DQM-5 speakers to try it out, I just inserted the 16 gage wires into the slots. A tight fit and it sounded fine. I just measured the width of the slots with a Starrett dial caliper and got 0.187″ or 3/16″ or 4.76 mm (almost 5 mm), allowing for a little width on both sides of the slot. I’m going to look for those adaptor plugs and also the male spade crimp terminals. Where can I get an Owner’s Manual? I can’t seem to find one.

  6. Hello everybody, i have the SX-300T and the transistors is in germanium, are the same thing for the SX-1000TW or TD?
