Nice job on the amp. Can you give us some details, tubes used, schematic etc. I like your oak chassis!

Regards,
Sal Brisindi

Thanks,..I can't post schematic without permission, I didn't get it off the net. It uses 2- OA3 VR tubes, 6zy5 full wave rect, 27 globes, Motor run & Solen w/ 2 chokes. 75v on 27 plates. battery bias using NiMH AA's. All in all the most fun I have ever had in audio bar none. Thing sounds damn good to boot, sorry about schematic at this time. Just that I would show a 1st time build to you hard cores. The oak chassis was thought of way in advance. I work with wood better than I do with metal so gave it a try. I am going to try a 26 next.

Very elegant.

You might consider taking the sticker off of the transformer.

Thanks for the sticker give away, I didn't even think of the sticky -gooie mess that it will do. I did learn NOT to put your rect so close to signal tubes..I should have put VR's & 27's much further away from rect.. I have small hum & shouldn't tried everything. I chaulk it up to bad part layout, but it is a 1st time gig. I will do better on the 26 next time. I also learned alot about keeping AC from DC in wiring,, the hard way..all leraning & fun for me.. Best sounding antenna you will ever hear.!!!!!!!!!!!!!
