I'm curious about these -- what's their reputation? How do they compare to Mercury Magnetics? What companies besides Geronimo and Valvetech use them? So many questions. . . .

My Reinhardt Titan has one and it runs on 10 most of the time with no problems whatsoever. It's loud as heck, but the tone is fully saturated and dripping at that point. I love it!:dude!

i did a Pro Jr project and put one of Graydon's (GDS) Heyboer OTs in it and wow! An amazing improvement in every department! It was phyiscally almost three times as large as the original Fender OT. In a nutshell: more volume, more tone, more dynamics, more harmonics.

Never tried one but the reputation seems to be sky high.

You might wanna check out the forums at www.ax84.com and search there. It also doesn't need any registering to ask about the trannies.

Heyboer is good people with a good product. Phil Dannenburg took good care of me on a custom JTM-45 wind - he's their VP.

Well, I'll find out soon enough in two ways... I'll take possession of this: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=38075&item=7325603186&rd=1

in less than two weeks. Yep, bought it from rwe333 here on the TGP, since I
always wanted a KT 66 tubed amp.

And I'm using the Heyboer trannies in my latest creation, the (quad 6V6) Capt. Crunch model... so I sure hope they sound as good as everyone says they do. I'll let you know in a few weeks!

Doesn't the Komet 60 use a custom Heyboer made-specifically for and ONLY available to Hogy and the gang?

I use only Heyboers in all my amps. There are other good ones out there but Heyboer is close to me and easy to work with. I like them alot.

I use heyboers in my 18, and 36 watt amps, and have been very happy with them. Also have used them in a couple of kt66 based amps with good results too.

FWIW, Heyboer OTs were original in many 'wrecks. I first tried them 15 years ago when everything had to be special ordered (they did not have a line of "canned" OTs). Always way overbuilt both in freq range and wattage handling compared to off the shelf type replacements.

Heyboer is one of the transformer companies I used/use for my amps. I think in general they make very good products and I don't hesitate to recommend them. However I leave myself open to using other manufacturers for certain designs--it's about whatever works best, not about brand-name loyalty.

So were some "hifi" Hammond designs. :) Some of those actually sound great for guitar amps. Not all of them though, at least IMO.

Thanks for all the replies -- sounds like they're well regarded, plus, they're made in the enchanted mitten. I've only knowingly played an amp with a Heyboer output transformer and choke once when I tried out a Valvetech Hayseed -- sounded wonderful, like my old AC30TBX but with a boomier low end.

Greg Germino has moved over to using Heyboers now, and I'd take that as a serious vote of confidence by a guy who simply uses the best parts that deliver the sound.

He mentioned that Heyboer is now making a dead-nuts copy of the original 50w Drake used in the plexi Marshalls. He put it into the hybrid Custom 40/JTM 50 that he built for me earlier this year.

Looks like I'll be trying them in a '71 Super Lead. They do come in the Germino's, and I know mine sounds great...so they should be cool in the Marshall....I have high hopes!!
