Product Reviews
Nice replacement transformer for a new Fender Champ clone build. Tubes and more always has been a great supplier for my needs. If they don’t have it on hand, they usually have a quick turnaround restock and in todays delivery debacle seems to have weathered the storm.
If you’re hard-pressed on money this is a decent low cost output transformer for single-ended amplifiers, the off center 5k tap can be used as a screen grid tap for ultralinear operation.
