Thanks Bruce. I've got your project posted on the site now:

JBAA - High Fidelity Tube Junk Box Audio Amplifier - http://diyaudioprojects.com/Tubes/Junk-Box-Audio-Amp/

I've also got a submission from Mark now and will get that posted soon.

Cheers,

Good work Gio.

Hi Mark, Thanks, The 6Y6 one sounds the best to my ears, but the 6AQ5 one is prettier. I like wood and chrome for current builds mostly. But JBAAs are from what ever is on hand. Each of the two amps were built on chassis that were from defunct projects. Even I (especially accourding to the "other one who is all knowing") make mistakes and dud projects. 8-)

BTW, many of your offerings are really nicely done too. :beerchug:

Good listening
Bruce
