I have been building small projects since the 1960's, and worked as a tech in NYC, while I was i electrical engineering school in the 70's. I am trying to renew my happy, and would like to build 300B SE amplifiers, and a phono preamp. I'm happy to behere, and hope I can help others.

Hi welcome,

I'm sure you will have lots of heartache and pain trying to achieve your goal, but have fun anyway.. :D
Yes tube amps are interesting and there are lots of people building 300B amps at the moment.

Regards
M. Gregg

Hi, Welcome to the forums. 300Bs are not my cup of tea, but there are others here that will certainly be able to assist you. Phono preamps are a different story. I have posted both solid state and tube ones. Th SS is simple and hard to mess up. The tube one is a bit more challenging. It requires a fair amount of basic knowledge and skills. Grounding, shielding and layout are quite important. A clean power source is equally important. As with most high gain tube circuits there are numerous ways to botch it.

I've been to Connecticut (first two years of college), my wife is from there...I much prefer the sunny high desert in Arizona though.

Good listening
Bruce
