Great Accessory  Time owned: more than 12 months
My older tube radios operate superior to radios directly connected to 120vac mains. The transformer provides a stabile B+ voltage including the fussy tube filament voltages. Using a Sola transformer will remove the varying line voltage creating a much improved frequency stabile transmitter & receiver. I buy these on the surplus market for as low as $10 for 250VA. My older Heathkit Commanche & Cheyenne Twins use a 250va unit resulting in stabile operation on 10 meters. The tube filaments now have regulated voltage, a function a 0A2 regulator tube can not provide. I recommend Sola and keep the transformer in a well ventilated area as they operate hot by design or called 'saturated' core.
A transformer will not increase the output voltage once the laminations are fully saturated. Sola is a simple design without fussy electronics subject to failure. Additionally, they provide clean power. The harmonic neutralized type units are best.
