    So i'm going to build a tweed deluxe clone with 6L6s as my first build. I've gotten a nice guy from TGP to tack some iron on to his larger order from Mercury Magnetics. I got the OT that is designed specifically to use 6L6s, but the regular power transformer. Now i've started thinking... can the PT really handle that extra filament current? Should I get another PT instead? I also plan on using an indirectly heated rectifier (GZ34) instead of the 5Y3.

    Thanks for any advice. Glad the page is back up!

    The GZ34 draws .1a less than a 5y3 so that shouldn't be a problem. 6L6GC draws .9a and 6V6 draws .45a, so a pair of 6L6GC's would draw .9a more heater current, you could check your xformer specs to see if the capacity is enough. I've run a lot of sf/bf deluxes on 6L6's with no problems but YMMV. You might also think about the JJ 6V6s which would run close to 6L6's in many respects.Hope this helps .

    And if the specs don't indicate what your looking for, ask the PT manufacturer, and I would guess they'll confirm that the filament winding in a rugged PT will probably handle the extra current without cooking (but it will age faster). By the way, if you're designing around 6L6's I would just call it a Super instead of a Deluxe.

    I sorted all this out. I'm using a mercury magnetics FatStack transformer instead of the stock one, it is designed to handle the extra filament current so all is well. THanks for your help.

    Brad,

    I hadn't noticed you here before, but I guess it's no surprise based on the content of our conversations on the DRC board. Good luck with the build. FWIW, Weber and SDG call it a Proluxe. I've got an SDG 5E3 with the MM trannies and it sounds great.

    yeah i had noticed you here before with teh Denton, TX address but didn't make the connection. This will be John's amp. I sort of miss Denton but i like it up here by NYC. I was talking to a guy today that I used to play with down there and he might fly me down for some gigs soon so maybe you could show me some of yr stuff since i never met you while I lived there.

    Cool. Email me if you're going to be in town and we can get the good stuff out to the rehearsal studio. There are a couple of other TGPers in the area that are usually up for a mini-ampfest.
