Bruce Moore Tube Amps

Thanks for the info Twl, I managed to find RB Audio through the search engines. I was really impressed by what I read at Home Theater & Hi Fi about the Dual 70 and Companion IIc, especially in regards to the midrange reproduction.

I've been very happy the last year with my Blue Circle BC21 and BC22, but I've always wondered how much better "better" sounds. I'm afraid if I audition something from Bob it'll never go back. Man, I'll never get out of debt.

Hi Guys,

Thanks for your interest in the products!!!

To answer the questions:

Bruce has been building this new line of tube preamps and amps since 1992, but most of the equipment has been sold over seas for the last several years. After filling an overseas order, any extra units that were built were sold by a few select dealers. Since the slow down in over seas sales in the last 2 years, I do sell as a dealer and distribute to other dealer.

I do have a demo program for customers and dealers for evaluation. FYI products can be seen on the web site: www.rbaudio.com

Any questions e mail bergner@pacbell.net or call 925-918-3714.

Questions on using different tubes in these preamps and amps please contact me for details!

Sincerely.

Bob Bergner

Gunbei: You can use either 6550 or KT88 output tubes with the Dual 70. I am using the 6550's that were shipped with the unit. Bob @ RB Audio suggested that I keep the 6550's since they sound smoother than the KT88's (my Martin Logans tend toward the analytical side). I did try JAN Philips NOS 6922's for the input tubes. The two outside tubes, of the four, make the greatest difference in the sound according to Bob. They sounded good, but I am sticking with the stock Teslas for now. I do have JAN Philips 6922's in my Companion III preamp and they sound great.

Thanks for the info Smerkle. As I get deeper into this hobby I'm starting to find that I like resolution and detail, but not at the price of musicality. It sounds like the Bruce Moore line might be a direction I may be taking. Once I get the cash. Thanks for tube rolling tips.

No problem Gunbei. You won't regret your choice if you go with the Bruce Moore gear!
