Title: Went back to tube amps
Post by: Response Audio on July 14, 2011, 08:54:53 PM
This is not a commercial post. Just wanted to share a personal experience.

With so much going on with designing hybrid amps the past year, I haven't listed to a tube amp at all :duh

Being a tube person at heart, I thought I would switch back to tubes today. I have a pair of custom mono bloc tube amps that I built about two or three years ago but never listened to them and had forgotten about them. Came across them this weekend and decided I wanted to see what they were capable of. They are constructed of solid Curly Maple and Bubinga all 3/4" thick. Right now they are running at 50 watts using EL34 output tubes with a 12AU7 input and 12AT7 phase splitter.

I had about an hour on them today which was plenty enough time to know that they will be getting a LOT more time on them from here on out :thumb:

No tube power all year? What was I thinking :duh

Ever so nice! I never got around to saying it but you make some of the prettiest gear in the biz. You damn well should enjoy some of your own creations  :thumb:

Thank you Shep for the kind words.
I am fortunate enough to be exposed to this on a daily basis but on the down side, do not have much time to build products for personal use.
At least these amps are mine and will not be sold. But you can bet they will go through some different stages of upgrades.  :D
I even have a matching preamp that was started some time ago but will be replaced with a Purity Reference in a matching Curly Maple chassis similar to Statement seen on our web site

Gorgeous amps Bill.  They would go great with my Figured Sapele/Curly Maple V1s! ;)

Best,
Ed

Thanks Ed.
As I mentioned, this was not meant to be a commercial post and these are not for sale but we could always build a custom pair for you. Did I say that out loud :roll:

Of course, the sound of these amps is the focal point of the conversation (otherwise, none of us would be here reading posts here on AN if it wasn't) but I have to say that your woodwork & finishing skills are absolutely exquisite!

Thanks again for all the kind words. Who's to say you can't have the best of both worlds with looks and sound. I don't think I could have a basic, plain steel chassis in my system. The various Maple grains and Bubinga have been a long time favorite of mine and when the matching preamp is complete, it should make for a nice, eye catching system. (and hopefully sound the part as well).

The speakers are large 3-way, 5 driver towers that I built many years ago. I switch these in and out with the Salk HT2-TL speakers with the RAAL ribbon.
