I know, I know - we've been through this, but recently I've come across some additional info that has me convinced we've not yet uncovered the whole Rocket transformer story... I'll begin with only the power tranny, believing that the output tranny may deserve a thread all it's own.
For many years, this has been the gospel of transformer knowledge concerning the Rocket... it has worked out well for lots of amp builds. I'm not sure if it's wrong, but I am beginning to believe it is not entirely complete.Allynmey wrote:Heyboer

The amp reported to be a JM build (see pictures) does not strickly follow the lead dress and color code of an authentic TW Rocket... but could be legit, I just don't know for sure. I was just beginning to grow skeptical that this was not a real Wreck build when that odd little 5v tranny has again showed up in a more recent revelation that I was provided.M Fowler wrote:The Rocket Jovanna has paper wrapped Stancor choke C-1002
75mA, 400 ohms DCR and 15H.
The OT in Jovanna is a dynaco A-470-s.
Another PT used in Rocket was the Stancor P-8356 270-0-270 (260mA), 5v3A, and 6.3v/8.8A
I have recently seen inside another authentic Rocket amp and it uses a Pacific power tranny and the 5V transformer inside the chassis much like the above mentioned amp. As another matter of interest, it uses the chicklet coupling caps.
I don't know how many of you have seen the original Rocket gut shot that has floated around here for years but does not show the actual power supply. Until now I am not fully convinced I've seen one before.
Now lets jump to another piece of folklore. Rocket #1 and #2 are said to be powered with the Stancor P-8356 that is mentioned by Master Fowler above. I cannot confirm this but the story has been told a time or two but folks that ought to know.... but in the last half hour received a report that this was another red herring?? It's hard to say...
All of these stories would totally change the reported voltages we are familiar with in the Rocket amp - YMMV?
