What speakers are you looking to drive with this flea on a flea amp? Good luck!

-but on what frequency?
-best NO crossover.......imposible or very hard to find such speaker.
Maybe a very good designed back loaded horn with a linear single driver responce (95-96 db spl,low mass cone,light bobin,soft suspensions)....will be a start to enjoy 2A3 sound.Placement in room (corners) to gain a few db on low registers ca be a plus.

Jervil: I have two pairs of Fostex FE206. One in a backloaded horn the other the simpler double bass chamber type. Should be 96db of efficiency.

I heard Joseph Esmilla's 171-A on his set up a couple of months ago. I think you're going to be in for a treat. Very nice midrange on those valves and a smooth relaxed sound.

Hi sir Tony,

Been following your projects over the years and your layouts are getting more and more refined. Are those copper boards you used?
