Rocket progress- from group build

[fishy]

Still need to power it up but I think I am ready at this point.
This is one of the group builds that RJ was kind enough to head up. I decided to do the cap stack and make a preamp board.

Still need to look at securing the chassis in a cab - probably will use nutserts...

A few pics. You cannot see the link from the treble to the bass pot but it is there....honest.

Is that .0047 Hi Cut cap soldered to both 220K?

[fishy]

Yes - as usual, the mistake seems really obvious once its pointed out.
Thanks for catching that.

Fixed that now.

[pureoldsound]

No problem Nice clean build..How does she sound....

[Tubetwang]

i like it!!!

Thanks..... should be firing it up this week...

how goes the Rocket?

[fishy]

Managed to check basic voltages without tubes last night. I have voltages where I expect to see them so I should be sticking some startup tubes in over the next few days.
Keep trying to get a variac so I can tame down my incoming but I keep getting outbid....

[fishy]

Fired up the rocket with some startup tunes in it. Didn't really play with it too much. Gets crunchy after 1 -2 '0' clock. Certainly not as "offensive" as the Liverpool.

I believe the only non standard items on the build are 1k screens and the coppertop.
If anything stands out to anyone, please let me know. As it is, I don't see much other than the hot biasing on the output.

Nice job fishy, she looks great!

[fishy]

Thanks Noel.
I have learnt a great deal from this forum in the last year or so. If I can make the same kind of progress recording clips, you might get to hear something half decent

Fish,

Just listened to your clips and I have to say it brought me all the joy and bliss of a new father... that is a great sounding amp!!!

I've been working on some clips for my own and have recently rounded some some great microphones for the task.

Great job on the build. We have all learned a ton on this exercise and I am stoked about the good results across the board.

BTW, my voltages on my 2nd build are pretty close to yours...

Thanks very much. I'm pleased with the build and with all the legwork you did to provide a good base, it came together quite nicely. Thanks for heading it up.
I will post more clips as they get done.
