Rocket Combo Takes Off

Post by rawnster »

The rocket build I did earlier this year was a successful build, at least to my ears. It does pretty much everything I want it to do. Yet, in the continual quest for better/different tone and some functionality, I decided to take the rocket preamp section and merge it with bigger bottle power section. Over course this is nothing new or earth shattering. However, I wanted to try it for myself and see what comes of it. Much thanks to RJ, Rooster, Fishy, Dartanion, Normster, for fielding my questions that were too stupid/novice to post! :) Anyway, here are some pics of the progress. I’m almost done. Just need to wire the pots, AC, and a few other things.

Basic tech:
1x12 combo design (matchless-style cab)
rocket preamp
--tone stack lift
--fat/normal/bright circuit
--single knob reverb
KT66 power section
Pacific PT/OT

Sweetly done Rawn, sweetly done. I like your layout and lead dress, very systematic. Can't wait to see it in its cabinet. Are you building the cab yourself? Is that one of RJ's chassis?

Dude, it's DEAD quiet! No hum, hiss, or errors. :-) I couldn't resist. It's not completed yet, Darin. Hopefully I can finish it tomorrow though.

Yeah, RJ's chassis. The cab is getting built by Peter at mathercab.com.

I love(d) my Rocket 2x12 combo. It was excellent, now belongs to a friend. I would love to have tried a one tube reverb in there. I'm building a 5E3 out of a hammond and might try it in this build.

How close together are your output sockets? I think KT66 needs more room from center to center for heat dissipation. If RJ cut the chassis though i'm sure it's adequate since he's done these before..

Ron,

That amp looks great :) and something I wanted to build based on Normster's Rocket Reverb using 6L6 or maybe EL34.

rj chassis will be delivered soon.

Thanks Mark. While I'm starting out with trying KT66's, I'll definitely try some el34s, 6l6s, and even kt77s. Who knows what will sound the best.

Any schematic.?
I'd be interesrted in the fat/bright switch, and how you insert the reverb into the PI.....?

I knew someone would ask for it. :)

I just fired up the amp about an hour ago. Got sound, the good kind! I need to check voltages and such to make sure all is stable. Also, after hearing it, it needs a few component tweaks in the fat/bright section and other places. The reverb is a little too subtle too. I need to figure out what's going on there. Let me tinker a bit and get things fixed so that I'll be able to share something somewhat presentable.

This layout was flipped to use one of Allyn's upside-down chassis, but it may be useful to help diagnose the problem.

Thanks Normster! Here's the actually layout of mine. Not nearly as pretty as yours. It's about 99% reflective of my build. :-)

Don't let that smoke out!
