I already have one of these and the Foreplay2 schematic. Could the 250volts be padded down to 175 or so to get the 150 volt B+?

Bottlehead PT-1 preamplifier power transformer

Our search for a cost effective, quiet power transformer for our Seduction phono preamp led us to having our own custom model made. With a large core and both electrostatic and magnetic shielding this transformer radiates less than 2/3 of the electromagnetic field of off the shelf models, making it a great choice where space is limited and the power supply sits close to the amp circuit. It turned out so good that we decided to offer it by itself. Super for line stages, phono preamps, mic preamps, active crossovers, any low level application.

Specs are

120V primary

250V CT @ 20mADC secondary

6.3VAC @ 1.2 A rms secondary

Made in the USA with channel frame construction, 2-1/2" mounting centers and solder terminals so you can use your favorite wire to hook it up. This transformer now ships with our current Seduction phono preamp kits and is essentially a drop-in replacement for the original Seduction power transformer, requiring only a little additional wire for installation. Intended for mounting on the underside of a chassis. The installation of this trans and the recommended Hammond die cast box over the Seduction preamp circuitry will yield a dead quiet tube phono preamp. This super quiet transformer can be useful in Foreplay mod projects too, by drilling new mounting holes and converting to a full wave rectifier. Price is $40 plus shipping.
