Deluxe Reverb, one channel, no tremolo

[telentubes]

Finally getting around to starting this amp project. I's a collection of leftovers, and my intention is for a simple grab and go combo with a little more horse power than my PR.
The PT is an Allen TP 40D, OT is a Classic Tone 40-18002, Reverb driver is a Classic Tone 40-18034, Choke is a Hammond 194A.
SOZO caps, and my usual curly maple face plate.

Looking good, and nice piece of wood there. Where did you get the chassis?

[telentubes]

It's a Watts chassis that has been several different amps, as you can see by the multitude of holes. 2.5 X 6.5 X 17.5".
I prefer wider chassis so this one got sidelined til now.
Sadly, Watts chassis are no longer available as they were a pretty good product.

I'm curious how you're going to label the faceplate. Love the curly maple!

[martin manning]

Thanks. Chassis and cabinet work seems to be in short supply these days.

rdavy,
Probably won't label the face plate as there are only 5 knobs in a standard layout. But I might. I thought I could use letter punches on the wood, then wipe a darker stain into the recess, but I'm afraid the letters would appear too ragged. I've used that technique on metal and it's a cool industrial look, but it might not transfer to wood grain. I'm up for any ideas. Laser engraving would be cool. Labeling the knobs would also be an easy solution.

Hi telentubes,

I'll be interested in seeing how this unfolds for you. I made Robinettes Blackvibe (VibroVerb normal channel) and while its a very nice amp, its just way to clean and I want to convert it into a single channel Pro-Reverb, which I suppose isn't very far from what you will be putting together (asides from power supply difference's).

Good luck with that project.

Best,

PJD3

I'm going to start with stock but I am also drawn to some of the grittier tones. Two amps with altered (enhanced) DR sounds that I'm intrigued by are channel 1 of xtian's "2023 Monkeymatic Whitney (Deluxe Reverb)", and rootz 6V6 amp from the "Two rock crs v3 clone and v1 vs v3 differences" post. Both have great sound and may be worth digging into more. I'm sure there are plenty more on this site, but those two amps come to mind for what you may be looking for. Me too.

I'm starting with stock tones (they are great) so following the DR values closely. There's one place I've found on various schematics that have different approaches in the signal path where it leaves V3B and enters the phase inverter. Specifically between the 0.1uf cap and the .001 cap.

Wondering if any of you with deeper understanding of circuitry have an opinion about the differences.
It seems it's just a difference of signal dump on it's way to the phase inverter mimicking loss from the tremolo circuit or master volume or mixing resistor. I am not going to have a Master Volume.
Here are three examples, either directly from Steve Luckey's "Tweed Deluxe Reverb" or builds "Inspired by" his Tweed Deluxe Reverb. Steve's is in the middle.
Thoughts?

Not much time to work on the amp, but made a little progress.

Looks great....as usual!

[Guy77]

Very nice! Congrats.
Yes a 5 watt diode laser would do the trick here for labeling and look really professional.
Cheers

Yeah, it's pics like that one that make me wanna build yet another amp
Looks fantastic!

[telentubes]

Thanks everyone.
I'm looking forward to finishing this project but
progress will be on hold as I'll be away from the shop for the next 10 or 12 days.

Here's the layout that works for me so far...
One difference is that there is not a buss bar. All the grounds are wire runs to bolts through the chassis.

Some progress.
