New R-Core tube Pre-amp Transformers

Zero Cool · 30th July 2010, 12:18 AM

I have access to a quantity of really nice R-Core transformers that were custom made for tube gear. These are brand new in the box. overstock.

The have dual primaries so they can run 120 or 240 volts.

Secondaries are rated at

#1 - 250VACFL @ .08A (+300vdc with 1060uf @65ma)
#2 - 10.5VACFL @ 1A (+12.6vdc with 10Kuf @ .8a)
#3 - 19VACFL @ .6A (+/-23vdc with 2x 4700uf @ .5a)
#4 - 8.3VACFL @ .75A (+10vdc with 10kuf @ .70a)

These have 7" Long leads and measure 65mm x 75mm in size.

These are really beautiful transformers that I imagine are over speced judging by the way the companies other transformers are speced.

$30ea plus shipping

psst. Jonathon Carr suggests using R core trafos for power supplies do to their inherent limited bandwidth that limits AC line noise.

I'm interested in one.
