A few toroids

imix500 · 12th April 2009, 08:09 PM

Hello all, I have a few toroidal transformers to get rid of.

1- Unmarked removed from a EV/Dynacord P1050 power amp. Includes PSU Board with one bridge and four ROE 4700uF 100v Caps.
Secondary 1 is 71-0-71. DC Rails sit at +/- 97v unloaded.
Secondary 2 is 23-0-23.
Also has I believe a thermistor to monitor temp.
Not sure of VA rating but the amp was rated at 550W per channel at 4ohms.
Toroid measures 165mm x 70mm with mounts. Includes pads and bolt. PSU board is 240mm Lx 60mm Wx 73mm H. $40

1- St. Ives Windings VT3022S removed from an AMEK power supply. Includes euro terminal block for mains voltage selection. Currently wired for 120v. Includes pads but no bolt.
Secondary 1 and 2 are 24-0.
Secondary 3 is 49-0. (For Phantom)
Not sure of the VA rating but outputs were fused at 10A for 20v rails and 2A for 48v.
Toroid measures 110mm x 72mm. $20

1- Nippon NU1A4b-0130 removed from a Denon CD Cart Machine.
Secondaries are being figured out, but there are at least 4.
Toroid measures 85mm x 56mm. $10
