Mystery Transformers

[bnwitt]

So I'm cleaning and organizing the shop and I found a box with three identical Heyboer power transformers.  I don't know what amp they are for, or their HT output.  Numbers are:


PT-250
HTS-12955
9961903


Anyone have any idea what I've got here?  Can't find anything on the web.

Thanks Shooter.  I already sent them and email and left a message on their Facebook page.  I just thought someone might know what these are.  I have a tendency to buy things on eBay and then shove them on a shelf.  It's like Christmas when I find them again years later but in this case I didn't leave myself a note on what they are.  I'm thinking they're Marshall 18 watt PTs but I'm not sure.

Wow!  I must have some really rare trannies here if no one has every seen them before.  LOL  Hopefully I'll get a reply from Heyboer this week.

maybe next time you go on a net buy spree, add a pack of sharpies for $2.99

That's right rub it in.    By the way, the real problem is Momma keeps taking my storage areas and I keep tossing my things around in a hurry after the evictions.

And my problem is that she keeps taking my Sharpies.
Doug lists a Heyboer PT-290 for 18W amps - its a 290-0-290 PT. So I have to guess you have 250-0-250. If you bought a "deal" they might have been PTs for an usual amp. Not very scientific, but I'd assume the 500 VCT measure it, see what the leads are, and compare it with the specs for other Heyboers you locate online. Or you could test it - I've only done that a couple times and have to watch YouTube and search here in order to recall how to do it.

Yep, been there too.

I think I bought these along with 2 combo cabs and one head cab from VHT amps after they stopped U.S. manufacturing and went to Asia builds only.  Maybe they are low HT vintage-ey PTs for these cabs which were 18 watt style amps.

Yeah I could pull out the tech, but I'm in the middle of several guitar electronics upgrades and building my recording studio around my Presonus Studio Live 32SX and upgrading cabinets and flooring in the upstairs bathroom.  And numerous other honey do's.  I don't need these right now but I had no idea it was going to be so hard getting info so I can label and shelf them.

If it is center tapped and is 250-0-250 it is probably similar to HTS-9144 which is a good replacement for a AC30.  Just a guess.
