Re: Rocket / Build
Quick shot of the cabinet/colorway... Still waiting on OT. I'm going to build the 2x12 cab this week... then schedule a time with my guitar teacher to give these amps a workout—and post some clips of Martin's Express and the Rocket in both threads..... I just don't have the skills yet—and he's got another speaker he wants to try...and is totally into it....(Oh, assuming the Rocket passes startup procedure and magic smoke stays in!!!)

Re: Rocket / Build
Just got notice the OT is in the mail! Will I finish the Dumble first?
Re: Rocket / Build
Yes I will.
(When I hear from Heyboer I'll buy one of their OTs too...for another build )

OT secondaries... and ready for testing/fireup procedure... plus bench insanity—I have lost my mind
The MM OT seems to have non-standard footprint—glad I waited to drill holes—actually a bit tight...maybe there isn't a standard though...

Re: Rocket / Build
An update... was inspired to fire her up... and... drama!!!
In short, no smoke, and 345VDC on B+1... but negative voltage on all the downstream caps??... That's a first for me. After verifying (again) all the connections in the cap stack... I figured either the standby switch is backwards (not)...OR... the choke is bad? I happened to order another 15H with the Mercury OT... So I took the Edcor out of circuit and it's reading OL.
EDIT—just put the Mercury in and she fired up—all normal—works! Can't play and test lest I wake the fam—but the Rocket lives! More later....

Re: Rocket / Build
Little update.... In comparison to the Dumble I just built—this amp was kinda loud in terms of noise floor... I coaxed the input lines which made a massive difference... also note that having the lid on—I made a cover for this amp, really a bottom cover—not sure if that's the normal protocol—but I can say that having some faraday cage action is night and day with regard to quietness here. Getting some really nice feedback and gorgeous chime-y tones (mini humbuckers) out of this thing. Definitely different than the Express...different brush as it were...Sweet!

Looks good!
Re: Rocket / Build
Yes on the coax and for sure these need the bottom plate.
Hiss is usual, but not as much as with an Express or Liverpool. Hum should be very minimal. Headphone trick for transformer placement is always advised.
Tube rolling has a big effect.
