Anyone used them or heard of them? I have a mixer that has a bunch of them (JBL 5600-2) They sound pretty good, but its a descrete FET mixer. I modded it to have 6 outs. I have another JBL mixer but it has JBL branded trannys. These are a standard octal metal plugin can. They are marked Sescom, Inc - TR-177a

I have a passive DI of theirs that's good, and a mic pre. I think they're known for good trannys.

Thanks Ubertar. I have been browsing their website but I didnt see any preamps, I think I'll take another look. Looks interesting, they even have some replacements for the Altec 1588A preamp cans. They still list a TR series, but nothing in the range of what I have. They do list an R-9 that is a replacement for the JBL 5195. This is prob the closest they list to what I have on the output. Its $130, if thats any indication of quality I hope the ones I have are that good.

I'm going to do a side by side with some of the JBL 5901 trannys.

They don't make the preamp anymore.

Check this out, they have lots of kits to build their audio modules, they even have a compressor:

They even have all their schematics

Looks like fun....

I have an EQ of theirs. Haven't used it in awhile, not sure how it's doing.

I got a couple of Altec mixers loaded with these (11 of them). The can says mc-1 (i think). I even took one apart, just to see the inside. If you're interested, I could take some photos. They're in my 1592 and the.....whatever the companion is to that with 6 pres (they aren't near me at the moment). I think they sound fine. Just a transformer some caps and resistors. I've never a/b'ed them to the 1588b, actually. Just never got around to it.

I've got this eq box of theirs. Unfortunately it didn't make it successfully through the shipping process and I haven't got it fixed yet...

I have one of the old blue passive DI's they made. I like it a lot. I use it on the return of a tape echo.... It is totally well made.

I have purchased a bunch of their transformers. I have four each of the ISO-1 and ISO-2 isolation transformers on hand whenever I go on location or run live sound so I can knock out humming DI or monitor connections. I also bought a pile of the loose transformers inside the line-level ISO tube so I could build them into our live sound rig.
If you have to buy a bunch of their transformers for a project, just contact them directly because they are very agreeable on pricing when you buy quantity, and they're nice folks.
