 New PS-25 Bipolar Power Supply
I have needed something like the new PS-25 for a long time. The PS-25 is a low-voltage, bipolar, voltage-regulated power-supply that is powered by a single secondary AC voltage, such as a 12Vac wallwart transformer or a regular power transformer secondary winding. $39.00 |  Introducing the new ACF 12Vac Rev.2 PCB and part kits. The key advantage to the ACF 12Vac is that it can be operated from a lowly 12Vac wallwart power supply, yet develops a fairly high-voltage B+ for the triodes and power the heaters with clean DC voltage. $29.00 |
