In Reply to: RE: has anyone compared Stereomour II and Fi 2A3 amps? posted by rockdoc on February 28, 2017 at 17:31:38
How do Cobalts sound? I was just getting into building amps when these were going away. Now they are unobtaininium. I need to update my profile page; here's the latest:
2A3 Mesh Stereomour II - TFA2004 M6 Nickle Pinstripe -10uF Jantzen silver - BCP15+, ViNi BCP 16+ Grid chokes, 0.1 Copper coupling cap and obligatto gold bypass on cathode cap and last PS cap, Shunt Reg and DC filaments to FE207's on a stick (OB on mic stands)
2A3 40 Stereomour - TFA2004 Mexico Quad PinStripe -5.6uF Riken- Dowdy choke, BCP16+ Grid chokes, .1uF Supremes bypasses, choke in PS to MMG's
45 - 5K EXO-145 Nickle Litz wire - 8.3 uF SiAuOil - Dowdy choke, .1 uF Copper coupling, .1uF Supreme bypasses, choke in PS, BCP-16+ grid chokes to Frugal Horns
45 Headphones- TL404 - 3.3uF Supremes parallel with 1.5 uF Jupiter Flatstack, PC-3 plate choke, 0.1 Obligatto bypasses to Oppo PM3's
Mainline 6C45Pi - TL404 15uF Jupiter flatstack to HD800's
2A3s on MMGs... no kidding! 86 db , how are they?
My cobalts are screaming to be built up; soon.... I'll probably build another set of paraglows with them, or might swap them into the amps I have..
It makes no sense on paper and all the forum gossip is that they need massive amounts of power but I'm near field (8ft away) and I'm satisfied. They have a magic with vocals and jazz. They could use a super tweeter and a sub but I knew that going in.
What are you waiting for, put those cobalts to use. They won't wear out and you can swap them into a new build in a hot minute.
I have 3 sets of outputs that need a home, but my latest wish list is for silver wire nickel pinstripe parafeed outputs to replace the EXO-145's I have.
So 2 2A3 setups, 2 45 setups, lots of Mike's iron
did you compare the TFA2004 M6 Nickle Pinstripes with the BH transformers stock with the 2A3 Mesh Stereomour IIs?
That one only had stock parts in it long enough to pass the voltage checks. It was planned for upgrades from the beginning. It went from stock to Nickel BH-5's then to the pinstripe TFA2004 juniors to the pinstripe 2004's. I would say about a month with the BH-5's, a week with the Juniors and now permanently (for the time being) with the 2004 pinstripes.
