content: Hi all,Little bit of a long shot but is anyone looking for reasonably heavy duty motors? They are untested but I have no reason to believe they wouldn't work, although they might need a little TLC given they've been sitting for approximately 30 years. The large one has definitely never been used, box was opened to take the photo. The two smaller ones were sitting as written off stock, however one is missing a screw on the cable cover so it might have been used for testing at some point. I have two of the smaller ones and one slightly larger one. PM if you would like more info. Looking for offers. Postage available at cost.Would be ideal for automating curtainsLocated in NE Scotland.Cheers.

timestamp: June 16, 2021, 07:04:27 am
content: Another piece of antique HP gear arrived with a missing button. Which makes several missing buttons now.The small square buttons. Colors: 1 x bone, 5 x green. See pics.Does anyone know of a source for these, or have some spares they'd sell? Or even some old unwanted boatanchor with intact buttons the same. I'd like to find a few more too, so I have spares.No luck with Sphere.Edit to add: the HP 8018A that is missing the 5 greenish buttons, could also do with a medium sized HP knob. See added last 2 photos. There should be two identical. One is mostly missing, the other has a missing top cap (but that I can improvise.) The intact one is off another 8018A. Shaft size is 1/8", 3.175mm.

content: Well that was unexpected. Apparently HP modified the shape of those little buttons sometime in the period 1979 to 1983. Who knew?In the pic the longer one at left is from lowimpedance, off a HP 1744 scope (introduced 1979.) Matches buttons on the HP 8018A serial data gen (introduced 1978.)The shorter one on the right is from the HP 5180A waveform recorder (introduced 1983.)There's a slight change of the inside dimensions too, but the longer one does still fit the latter 5180A. It's just quite easy to pull off, and projects a little bit further than the rest of the buttons.I'll measure the button lengths and add them here. Tomorrow.Last laugh award goes to Nominalanimal.Added dimensions (height, base square, mm):Long (1979): 10.7, 5.85Short (1983): 9.5, 5.7

content: Looking for a universal programmer (minimum 48 pin drivers and preferably with a DIP adapter) that has support for Windows 10 (connects via USB) - prefer externally powered (or internal PSU) so it can drive a fair amount of load. I currently use a Xeltek 500P which does the job reasonably well, but a little slow so would have to be faster (ie Xeltek 601P 611S 6100N, ELNEC BeeProg+, or similar).

ELNEC seemed to be on a good track up until BeeProg2 where I dont know how they sleep at night calling it a universal programmer anymore in that the adapters seem far from universal. I do like that they keep the drivers/support up to date though. For my 500P the last supported software was back in 2014.

You could either buy the whole thing and use it as-is (provided it's rated for 230-240V at 50HZ, from an AU or EU seller) or just take the part that you need from it. Alternatively, you could try messaging the seller and ask him if he'd be okay with selling you just the part that you need, and if so, maybe you could negotiate on the pricing! Good luck.

content: This may be better suited for a vintage audio forum but I'm already registered here and there must be some of you guys lurking. :-)I'll be posting pictures soon. In the meantime I'll try and do my best to describe it. The amp is in quite good condition considering it's age (usual scratches on the bottom, side panels, etc). The front panel is almost flawless. It doesn't look as though _any_ work has been done on this amplifier. Inside it's very clean. I don't see any resistors that look like they have been heat stroked. It has two stromberg carlson 6V6 on the output that I'm guessing are not original's. The preamps are using RCA 6SF5's (the metal can type). In the middle the output's are being buffered with a 6SL7. For what it's worth, the pilot bulb is clear with no visible tungsten burnoff. I removed the cord since it was literally hanging by a thread. I have not attempted to power it up.Feel free to ask if you have any questions. I will consider any sane offer so long as it goes to a good home. I'm also willing to ship the amplifier anywhere within the US (I'm located in Southern New Jersey).

The distributor catalogs would often have a few pages devoted to them, from little 5 W to maybe 100 W units, some with elaborate input mixing facilities. They were very similar, a chassis with controls and a cage cover.If you want to get rid of it, go to a swap meet, especially one that attracts collectors.

(However I totally agree that final spent time and forces on rewinding don't cost time I may spend on it, and it might be hard to guarantee the same quality, no doubts here).Thus, if somedoby has blown transformers (especially in EU, basically because of shipping cost), I'm open to proposals, especially for TR-280.(Potentially, I may obtain TR-299 for ~$90 or so +shipping and taxes, but I have one alive so prefer blown in this case, however if 2 alive appear for decent price, will be ok).Thanks
