Default My F5Tv3's

My F5Tv3 monos. Power supply comes out to +/-47vdc under load @ .7A (.350v) per device x8 with an Antek 800VA xfrmr and 88k uf per rail CRC. The small xfrmr is just a 10va for standby power to run the main power relay and switch LED. Soft start and speaker protect are both from the store. The 12Vac from the main xfrmr runs the speaker protect board and the soft start uses 3 CL60's in series in place of resistors. Case is the 5U from the store. Started out with the steel version then got the aluminum covers later on. The front panel was cut on my CNC, only .020" deep, then filled with black nail polish & the excess wiped off with acetone when dry. The rear panel text will be cut later. The Preamp in the last pic isn't finished yet. It will house the Salas DCG-3, a Velman pre at unity gain for the blasphemes bass & treble (for those difficult sources) that I can switch out of circuit & a small pair of VU meters. Hope you like

Merry Christmas to you! Nice and tidy. Fun to look at. Very nicely done.

I fear for the cat's life.

Aleph 5 in experimental stage. comparing Linear PSU 800VA 190,000uf with SMPS and less than 20,000uf.

SMPS is winning in my house.

Interesting.. I've often wondered as I'm running Hiraga class-a from SMPS
Would be nice to hear comparisons.
