JMPA Posted February 1, 2009 Share Posted February 1, 2009 Hi this is my first post. I want to know a good and cheap replacement output transformer for my valve junior. And if this transformer would work http://www.mouser.com/Search/ProductDetail.aspx?R=125Cvirtualkey54600000virtualkey546-125C Link to comment Share on other sites More sharing options...
cGil Posted February 1, 2009 Share Posted February 1, 2009 Nope. The Hammond 125C is a universal OT for a Push-Pull amp. The VJr is Single Ended. Wrong impedances for the VJr, too. The VJr needs a 5k primary winding impedance, and the secondary winding should have at least an 8 ohm tap, if not 4, 8, and 16 ohm taps available. Hammond OT's suitable for the VJr are as follows: the 125CSE is the minimum size required for the job. the 125DSE is a popular choice for the extra bass it offers a single el84's tone, or the option of parallel el84's and/or 6V6's, or a single 6L6 or EL34. the 125ESE is also popular for even more bottom end with a single el84, or the option of larger parallel power tubes or simply bigger single octal power tubes like the 6550 or KT88. the 125GSE is the OT of choice for getting 25watts out of a KT88 with 450v+ on the plate. You'r gonna need a bigger PT to pull this off. Other OT's to consider are the OT8SE, OT10SE, or OT20SE series from MPS. http://www.musicalpowersupplies.com/ And then there's the Edcor, which normally isn't available with multiple speaker taps unless you specifically request it. However, Edcore may not even offer the multi-tap option anymore from the rumors I've heard. You'll have to check. But I don't have the link. Sorry. Gil...
