I just want the tubes

I've been waiting on the PCB's since they were first announced

I'm definitely in when this goes thru. I check the forum everyday just waiting for the GB.

Hm, so I've finally gotten started on this project (just got back into town). Two short notes:

1. Wow, Mr Maher, you were correct - setting up the enclosure is at least half the battle!

2. It looks like I've ordered/received 220uF caps instead of 150uF. Not sure why, maybe the BOM was updated and I'm just reading outdated posts in the thread, or maybe I just intuitively substituted :p. Theoretically this'll provide a bit less bass cutoff and a slightly easier start for the power suppy?

Here's quick phone-cam pics of the small holes I've already drilled and positioning of the external parts on top of the case:

Tight squeeze! I might actually go with a 1/8" headphone jack on the front panel for this reason alone.

Looks good though

Also, has anyone tried this build edit for the 12SR7GT tubes?, or the 12SR7's?

How does it sound? And is all that you have to change the tubes and the resistor values? Everything else stays the same?

Then you take the small plastic washer which goes into the mounting hole of the MOSFET through which you wil put the screw. You need this plastic washer without which the screw would short the heatsink and the MOSFET tab.




just like to add, if anyone is wondering What happens without the insulator is that you will see you SSH spark up all over the sinks and around the case it keeps going after the power is switched off. you could say my first p2p effort was bit too bright

Ugh, because without being able to find 19J6 tubes, I really want to find another option for a hybrid amp to build, but I want to keep it relatively cheap. So i'm thinkin either 12SR7GT, or go for the millett maxed

Haha, I'm trying. I'm emailing everyone out there. Wish me luck

cms5423, I would've waited for the beezar kit.. no guarantees but a good probability you'll get one as tomb *may* let first time builders get first dibs on these kits

Tomb, what's your plan when they go on sale... will it be first come first serve?

Yes, I don't know how it could work any other way. I'll give plenty of notice, though.
