Starter suggestions?
 
Hello,

I'm new to this forum, but thought i'd jump in feet first....

I'm in the middle of a multi-amping project. What started as a two-way has now grown into a three-way architecture. So, i find myself looking for an [affordable] amp for the top end driver (tweeter, plastic dome, B&W 801).

Naturally, my thoughts drift to a tube solution. I'm kinda sold on Class-A, SE and can easily 'live' with the related [power] inefficencies. So i'm thinking that 3-10 watts is about right (bottom is 100wpc SS, mid is 30wpc MOSFET). Only has to handle 3.5KHz and up.

Maybe EL84s?, maybe EL34s?, maybe 2A3s?

NOS or 'new'?

If NOS: which of the 'available' units would be my best bet [other than Dynaco ST70 ;) ]? I'm a tweaker, so mods are highly probable and "classic" value is depreciated. I'm sure there's a pandora's box of opinions on this subject, but i'm hoping for some guidance that centers upon my particular needs.

If 'new' (read: DYI, Kit, not retail), what/where should i look for things "up my alley"?

Thanks in advance for your kind thoughts,

LarryO

You should use single ended for tweeter and midrange. You donīt need much power there.
Single ended mosfet or valve is personal taste.

For the bass I donīt know. A valve amp at high power is very expensive. I like the EL34 and the 6550 in ultra linear puch pull topology.

The new versions are very good. Something from Svetlana is very good.

Something to look at. http://gabevee.tripod.com I just built the CGV 0606 and I couldn't be happier with it. Got lots of support from Gabe as well. I also agree with using them for mids and highs. SE tubes are a lot smoother and more detailed than SS. At least this amp beats out my A75 and I didn't expect that could be done. Good luck


P.S. The sound is in the tubes so buy the best that you can afford.
