reVintage Audiophile Posts: 120 Location: Eskilstuna Joined: June 19, 2008	Aha, So it wasn´t a 2A3 amp you where building ;-). 3,5k primary indicates you are aware of the fact that JJ 2A3-40 is their 300B with parallelled heaters instead of series connected. Brgds Lars

slownlo Audiophile Posts: 1080 Joined: October 11, 2003	Thats one of the benefits... Internally, the JJ-2A3 is nothing more than a 300B with a 2.5V filament

Appearance reveals an inner beauty that no amount of gilding can improve. You'll like the JJ 2A3-40 tubes i think. Congratulations and Happy Listening. The double diode looks like a 5U4 or is it a 5R4? The base looks like Micanol.

slownlo Audiophile Posts: 1080 Joined: October 11, 2003	Well.... (lol), You know how these things go....once I start slinging the solder its anybodies guess what it will look like under the hood...the goal though is to try and get it as neat as possible as long as it benefits the sonics! Navy won, but the Irish came back strong during the end...

Yeah watched the game. Quite entertaining. I know Charlie Weir is a nice guy, maybe even a good recruiting coach. But, he does seem to be a step behind opponent's play, at times.

I try to make things neat. Maybe too obsessive. As tone, low noise, & reliability is the ultimate judge. I guess after getting some units returned to me & saying: "Man, who did this abortion-of-a-setup?" I've taken the mil spec approach to layout. Does make fixing the thing, at a later date, easier.

Good job. Enjoy the tunes, through the amp!
