Guitar tube amp OT Calculation/Winding HELP!

[mirkoslav]

Hello everybody!

I'm new to the forum so first I'd like to say hello to everybody and please excuse me if I'll ask a question already asked before.

Since there are many smart and experienced people here, I beg your help since I am kind of stuck. I am trying to make few replicas of classic guitar amps for me and my friends and need output trannies but don't live anywhere near the States, and shipping costs + tax + duty + handling + ... would be too much. There is very little info on the net about actual calculating, designing and making blueprints for a hi-fi OT's and absolutely none I could find for good sounding guitar OT's.

Since they are kind of different in philosophy, I am sure there are smart and experienced people here who have real world experience with good sounding guitar amp OT's so I'm kindly asking your help. I am not trying to steal anyone's business, and have no intention publishing any information given to me by anyone who wouldn't publish them by himself.

I'm trying to make a Bassman 5F6A replica or a Marshall JTM45 replica because I could never afford the reissue, let alone the original in a million years. So that would be a 6L6 push pull guitar output transformer or a EL34 guitar OT. I have found a craftsman who would wind me the OT's but I have to give him a detailed blueprint. Please HELP with core sizes, number of turns, winding/interleaving layout etc etc!

Thanks in advance for any help and sorry to bother you all!
