Whose Pacific Wreck Transformers are these??

[RockinRocket]

I'm not familiar with all the Pacific makes for wecks. I asked the seller and was told they are about 10 years old. Any one have info one them? Are they as accurate as RJs and RockingClass?

Those look like Heyboers to me. Labels do too.

Heyboer. #996

They look like the new Rocking Class Pacific to me and the labels have Pacific part numbers.

I almost bought these now im glad I asked. They do look like my rocking classes from what I remember but the label looks likemy hybores like Mark said. Thanks folks!

They look a lot like old Heyboers... I have a photo of an old 120/240 Heyboer Wreck PT and it shares some numbers with this set. The primary number is a Pacific Number but as you can see, Heyboer did use them at one time.

If you can see the mounting tabs you would know for sure. Pacific uses a heavier gauge steel for the end bells. Also, the varnish runs are a common thing in Heyboers and i've never seen it on a Pacific.

Edit - I found another photo that has a set of these in it - Something I sold or put together a long time ago and for whatever reason I took photo to show the options for Heyboer trannies. If we compare the lams and endbells as well as the labels then it makes it pretty clear.

Thanks for the photos RJ! Unfortunately I'm a bit of a dumb dumb. The 3rd photo has no name and the endbells wrap around the transformer a bit different. What make are thoes?

"HTS" part number and 996 EIA code both spell Heyboer.

"HTS" part number and 996 EIA code both spell Heyboer.

Correct, wound in the 8th and 9th weeks of 2005.

They look like the transformers Moose was selling way back.
Heyboers I believe. Good iron.

[RJ Guitars]

Yeah, it's another version of Heyboer. They have used a few different end bells and I've seen a handful of part numbers. I think Rob Hinson is the guy that originally worked with Heyboer to develop the Wreck trannies.

I'm aware of two different styles of Express OT that Heyboer provided... and there could be more. I never received any of them with the Pacific part numbers directly from Heyboer but I did buy a couple of them from Moose before he blessed me to continue on his tranny supply efforts. (In my archives
I have a very cool email from him giving me the nod to carry on).

Both of the part numbers I used had two primary taps (5.2K and 6.6K). They were wound the same but the cores were from different alloys. The difference in them was a change to M29 steel and was referred to as "the vintage" Wreck OT. This Heyboer vintage tranny is a killer sounding output tranny in an Express.

[RockinRocket]

Rj is the "vintage" heyboer replicating the Stancore?

Forgive me as I have forgotten, but has it been debunked that Heyboer was never a original transformer for Ken as the seller has it listed?

[RJ Guitars]

I am not the ultimate authority on this but I do recall that "SelloutRR" from this forum dug deep to determine if indeed any Wreck had Heyboer trannies in it and he proclaimed that none were ever made. He had access to the Trainwreck records when he became the West Coast official service center for TW so he probably knew... FWIW I can't say for sure.

I did have a conversation with Phil at Heyboer one time where he said he was looking at a set of notes and specs his dad created for Ken Fischer for an output tranny. He made up a batch of those trannies for me and I used one in the first Rocket amp I built. I now recognize this was not the right tranny for a Rocket but it is a sweet sounding unit and I've never changed out my Rocket tranny for fear I might loose something. Attached are photos and curiously I just noticed that they have the Pacific part number on them.

Interesting thing here is that for Heyboer to have these part numbers might imply that they were copied from an original Pacific unless maybe Pacific copied from them... I sorta doubt that.

The Pacific output is very much a copy of the Stancor 3801... you can sorta see it in the size, wattage, primary impedance, and the odd 15 ohm secondary tap. I consider Pacific to have much better quality control and the resulting trannies were were better made and more consistent from unit to unit than the stancors they were copying.

One interesting but maybe not entirely relevant tibit is that I have talked with John Mark a few times and he swears the old black 3801's are the ultimate and he likes them even better than the gray ones.

[RockinRocket]

Very cool history there RJ! Looks I'm going to pass on them transformers. It would have been a great deal if they were Pacifics.

[RJ Guitars]

I meant to mention that I'm working with Rockin' Class and I'm able to match their online prices... and even offer trannies a little cheaper in some circumstances. i haven't put any info on my web site yet but hopefully you all know there is always a better price for parts for anybody active on a forum.
