Hot Rod Deluxe PTP conversion

[Bob Pollock]

Hello, I'm new to this forum and in need of some suggestions.
First, I'll state that I'm familiar with tube amp repairs, quite adept with a soldering iron, and well aware of the related safety concerns.

I have a 10 year old Hot Rod Deluxe that is exhibiting the typical issues. Without wasting time detailing those, I'd like some suggestions as to what hand wired, eyelet/turret board circuit might be adapted to use the existing chassis and transformers, and the 2x6L6 format? I'd like to retain reverb, but that isn't essential. I'm looking for a clean pedal platform, so no channel switching or master volume is required.

Thanks for the link, but I'm not sure what you might be suggesting. I'm not interested in pursuing anything related to Torres Eng.

Well one can learn from the photos and information that you now chassis mount your tube sockets rather then PCB.

You decide on what circuit you want in your amp then make the board. You need to decide what features you want to keep on your faceplate, Reverb, channel switching extra.

Thanks. I'm aware I'll have to chassis mount the tube sockets. I guess what I'm looking for is recommendations as to which of the traditional circuits might match up best with the existing HRD transformers, 5E3, 5E5, 5F6-A, 5E7???

The HRD is called a Deluxe but clearly is a 40w 6L6 power tube based amp so it's closer to a Bassman then a Deluxe.

Any circuit using 6L6 can be mated up to work. The Hoffman forum has a lot of .sch format schematic and layouts available.

Heck this forum is loaded with past projects, take a week and look at old posts, that what I did when I joined.

Hi,

5E5-A or 5E7 are great amps fixed biased amps fueled by 6L6s (slight difference on the NFB resistor on V2). My son as a rare version with 3 6SC7 tubes in place of the stock 12AY7 12AY 12AX7. It takes pedals as does the stock complement with ease and the clean is to die for.

I've worked on 5E6-A (similar to the above) and 5F6-A vintage amps, had two side by side from clean to full bore. With my eyes closed and A/B with a guitarists and an A-B box, it was hard to to tell the difference.

The 5E5-A has one 15" speaker (Alnico), the 5E7 3-10", and the 5E5-A as you know has 4X10", different OTs.

Since you are going to the time and effort of PTP (Circuit cards), you might want to invest in a new speaker (or speakers) and replace the Fender stock lowest cost they could find from an OEM if you haven't already done so. A replacement cab offers some sonic benefits, but replacing the Fender's PCB (Piece of Crxp Board) with its inadequate copper traces is a good start.

Best of luck and welcome,

Steve,

I'd like to retain reverb, but that isn't essential. I'm looking for a clean pedal platform, so no channel switching or master volume is required.

I`d go with a SSS platform, minus the reverb stuff and the filters, that produces an incredible sound on it`s own ( can verify w/Fender Blues Deville modded to this) very simple, you could practically build it w/in a week part time..

The stock HRD OT is horrid sounding.

Not a good part to keep.

Thanks Steve. I appreciate those suggestions, and I put a Celestion G12-65 speaker in it already.

Thanks Jim! I've entertained the thought of a non-traditional circuit too.
Would you happen to have a link to a particular layout or schematic?

here`s a 70`s circuit i did on a S2 amp conversion layout, i added the red boards for the OD..
