Here’s a site someone on FB just told me about:
I used to buy stuff from Halted sometimes. I went to get a link and found they had been bought by excess solutions. I have never bought from them and know nothing about them. They do have some useful stuff, including an AMI version of TI’s 9900 processor.

One place I like to buy a lot of parts from is Tayda Electronics. I believe they are based in China, and have prices close to ebay direct from China. But they have a warehouse in the US and I believe in Europe. It has never taken me more than a week to get stuff from them. Typical is five days. They sell a lot of stuff for hobbyists, but some of the stuff they carry is older stuff that should be of interest for retro computing. For instance, I bought several 74LS181 ALUs from them a couple years ago. They still list them but have been out of stock for a long time. They did get more in once after listing them out of stock, so maybe…

Oooh! Silicon Ark had some unobtanium LED drivers I need for a current studio preamp project I am embarking on. AWESOME.
Someone hipped me to Excess on Masto the other day and I already had it on the list.
Here’s a very specific one I found a few years ago. I was going to be in need of a vintage can capacitor replacement for a 1966 Heathkit tube hifi amp kit I have. I could have taken it apart and restuffed it, but I found a company that does this, and they have the best name.
Hayseed Hamfest:

So I actually ordered the can capacitor from them and and I wanted to show it off. It came in yesterday’s post. Can’t wait to finish this old Heathkit amp. But then again, I’m, building a few SSL 9000 clone mic preamps, 2 Urei 1176 clones, and any number of other small projects to support my live sound gigs.

I have Hayseed Hamfest caps in a Drake TR-4, Drake 2-B, and I think a Central Electronics 200-V (I’m not 100% sure the latter is Hayseed, I don’t remember). I’ve been very happy with his parts. He can also stuff custom capacitors, given specifications. I quoted one of those a few years ago (for the CE transmitter) and I recall thinking that the quoted price was quite reasonable.
This one was custom.

Hi,
Thanks for all the suggestions for suppliers of vintage parts. I’m trying to design a 4-bit slice using TTL that is actually still available.
My biggest problem is the 74xx189 a 16 word x 4 bit RAM. There were about 4 versions made, true or inverted outputs, open collector or tristate outputs.
I see that Jameco still have some stock, but then you have to resort to eBay, or the vaguaries and risk of purchasing generic Chinese sourced parts. There must have been many burned by “fake chips” - just a lead frame and plastic package - with no die at the heart of it.
I hope to put together a small pcb that contains a useful 4-bit slice. Sadly this may be thwarted by the non-availability of small 4-bit wide RAMs

Yeah, eBay is tough. I needed some 2n3819 JFETs and those can still be found from NTE, but I wanted to find some NOS Fairchilds or something. Everything I ordered from eBay was bogus. I complained and was able to get my money back, but ended up finding them from another NOS supplier in the UK.
I just got some LM3915 LED drivers from Amazon. Those are legit. I also got some from some other suppliers, but everyone on the list up there ^^ are places people have vouched for, and I have used many of them.
Didn’t I post a list of all the sites I had collected so far, here?
Also, I just want to give a shout-out to Jerry over there at BG micro.
I ordered some chips he had listed on his site, and they didn’t ship right away. I ended up ordering more from Silicon Ark, and I finally reached out to BG and he said he was out of stock and didn’t realize it, but had more coming in. I waited a day or two and asked him to cancel the order. He told me he had already shipped it, but he would refund me if I wanted to send them back. I told him I would send them back because of that 2nd order I did, and he credited me the cash immediately, even before I had sent the parts back.
That’s some good service right there.
So here is the list that I have so far. This is a work in progress, so more submissions are always welcome:

I just found another place through a Youtube video. It’s not a general surplus shop, but I bet it will come in handy for a lot of people.
They sell hard to find and re-manufactured TV parts. My dad and I have identical Samsungs that had their famous power supply problem. Someone at the factory put 10 volt electrolytic caps on 12 or 18 volt rails, and in time, the caps failed. Anyway, we fixed that problem ages ago, but I guess over time, the dirty voltage the PSU was outputting causes issues on the motherboard.
So I found two MB’s from these guys for like $21 each, with a 180 day guarantee from this place.
They get great reviews so I ordered two.
2901’s are getting scare, so now is a good time to pick one up.
Remember Arcade sites (on the web) are good places to find
and have burned small fuse proms.
74LS170’s make a nice ram for small 4 bit slice.
I use Unicorn electronics https://unicornelectronics.com/
Right now I am doing protoyping in a Altera De1 FPA prototype board
usiing TTL macro’s. Once I get the hardware and software down
I can later move to real TTL with less unknown problems,
as I wlll have tested and proven several ideas.
72 pin (1.56 inch pitch) Bus connectors had to be found on ebay
as well as a small power supply.
74x163/74x157/74x170/74x181/74x195/74x4 bit buffers
is what I am using as generic 4 bit slice.
