Dear Mr. Fujita,
First, I want to reiterate that I am getting a lot out of your teaching. I am using my ears now, and surprise surprise, they work.
The purpose of this message is also to ask you for a recommendation for a Fender tube amp repair expert, in the Boston/Cambridge/Somerville/Arlington area preferably.
I hope you will have time to get around to reading my email.
Regards,
Jerome Oks
