Bigger Tannies + 6l6 in a Tweed Deluxe build...?

    Is there anything I should be aware of that needs to be done if I make a Tweed Deluxe amp build with everything the same as a typical Deluxe circuit but with the output and power trannies of a super reverb? (I would then use 6l6 tubes and a SS rectifier)

    I'm assuming I'd need to up the power filtering. But how much?

    You're basically talking about a 5E5 (narrow panel)Pro minus one of the preamp tubes/channels. It employ's 2x16uF caps before the B+ dropping resistor. You could go with 40uF 500v cap if you need the space, 2x20uF would be better. You might consider using a choke between the OT & the screens instead of the dropping resistor.

    Thanks...

    Yeah, I will probably use a choke since this project is inspired by a full set of extra trannies I pulled from a project that I upgraded to Mercury Trannies. So i've got a Super PT, Twin sized OT, and a choke to use.

    Thanks! I'll probably try to fit 2x20uf filters since it would be a lot safter since the voltage from my PT is nearing 470...

    I built a Tweed Deluxe last summer for a guy who wanted " Neil Young ". I used a Blackface DR PT, 6L6s', 5U4, choke,( which I finally removed ), and a Super/Bassman OT. After A/B-ing the tone with/without the choke several times, I decided that the choke,( with this particular Heyboer PT, which has a HV secondary of 350-0-350 ) sounded sterile, and took away the "fun-factor" when playing lead. Also... I would use the 470 ohm screen , and 1.5k grid resistors on the output tube sockets, ( like a Blackface ).

    i recently built a 5E5-ish head for a local band---he wanted a high headroom version as he uses a pedal for OD tones---- he also wanted a brighter overall tone response---- single channel--- both sides of V1 run in parallel---- 125C1A choke---- 5U4GB rec--- @30 watts output into an old 4x12 Fender Bassman 100 cab.
    He's very happy with it and the band's lead singer/2nd guitarist has been talking to me about building a similar head for him but voiced somewhat differently for his requirements.................gldtp99

    Check to see how Steve Gupta (SDG Vintage Amps) does it with his "Proluxe" amp. It's a 5E3 circuit but with larger iron and adjustable bias. 5AR4 and 6L6s or a 5Y3 and 6V6s....
