Very bad poor quality

After few hours the tarnsformer is short circuit. Shame, how it's possible... I build many many amps in a year. Chinesse shit products.

Admin 4 Jul 2023

Sorry to hear about the bad luck witt the 125P1B mains. this transformer you are having issues with is made in Illinois, USA (as stated in the product description) and meet the highest quality standards in the business. this is the first warranty issue for this product since over 500 units sold from last production run. there are multiple reasons why a transformer could fail....

11 Aug 2006

B+ Secondary voltages (primaries wired for 240v) come out at 367-0-367 in the UK. Plate to ground voltage with a 5Y3GT comes in around 418v in a Champ (stock 470ohm cathode resistor, 23v at cathode).
