Just read the guide; really, really cool and interesting to read. Definatly sticky material! Great work Silverwulf! I look forward for more. Thanks for sharing your hard work, research, and years of knowledge!


Thanks! It has a long way to go, but I think it's off to a good start. I'll go back through today and clean up the typos after my morning coffee from typing at 12 AM... :mrgreen:

Thanks for the effort. Also, those are some nice PCB shots. Some initial thoughs:

Compared to rev C+, there are some minor layout changes here and there on the clean channel. Other than that and the mentioned caps, it seems to be pretty much identical. Rev D seems to introduce some other changes, but I need more quality PCB shots to confirm.

Those larger filter caps Silverwulf mentioned are in the low voltage supply circuit and shouldn't have any effect on the tone - unless there was something considerably wrong with it to begin with. Are the B+ supply cap pairs 10uF/450V? If those would be 15uf, that would definitely make the amp more akin to the 2 channel model.


I'll take a few more shots the next time I have the chassis out. I'm trying to take relatively hi-res shots so folks can zoom in as far as they like.

Rev C and Rev C+ are fairly close indeed. You'll see when Rev C+ is updated soon, but there's a few other differences as well. I'll try to get that updated today.

I guess it begs the question if the transformers in later models introduced some of the fizz? I assume you have played professionally modded amps, like Voodoo's Recto. Could you comment on Mercury transformers?

My tests have included DI to my Nova System from the Send jack. The preamp sounds much clearer and sharper through the NS than through a cab. I know the power amp lends a layer of fat, but I haven't found a definite cause of fizz in it. A transformer update would make sense as being a cause.

I have a 3 channel recto that to me sounds a little different then others I've played. The serial number is R- 017437. My question is .. Is this a Revc? Mine has no line above the output and solo controls, the trademark symbol is there also. The power tf is 562105. Any help would be great.

It sounds like it may be a C. That serial number falls in between the known serial number cut-off points that Silverwulf has noted that the revision change likely occurred. If you feel comfortable enough to pull out the chassis you can confirm for sure.

Rev: C+
Serial: R-0285xx
Brackets and "Loop Active" are present.

Sorry for the delay. Work travel and life in general, but now I'm back again... :mrgreen:

It would be really interesting to know what this one is! Cosmetically, all signs point to Rev C, but this is also right around the time that the transition to Rev C+ started happening, so there's some chassis overlap there.

Right now, the earliest confirmed Rev C+ is R-017882, and it also has the 561140 PT in it. So, the 561140 PT definitely extends into the very early Rev C+ models. With that in mind, if yours is stock, it should definitely have the 561140 PT in it. The 562105 is the Dual Rectifier OT.

If you're ever up for pulling your chassis, this one would be great to know! That would either narrow down Rev C to lasting into the R-017430 range, or it would drop the confirmed start date of Rev C+ down by over 400.

This is awesome info! Very helpful. You just extended our known serial number range for Rev C+ by almost 1500... 8)

I need to add your name to the "SPECIAL THANKS" section in the guide. Off to do that now...

I don't how far in the timeline this was done but with my (2nd) 2008 3ch Dual Recto, both gain pots measured at 100k instead of the aforementioned 250k, even with EMG 81's I had to max the gain at low volumes and ran it around 4:00 at band levels.

I remember another forum member R_ADKINS80's 3ch Triple also had 100k pots, it was either from same year as mine or 2006.
Mine came stock with the 440's, I didn't have the older one for long, most likely had the 430's in them.

When I played my first 3ch Recto back in 2002, it didn't sound like the one mentioned above, and I had the gain around 1:00 and it was enough.
I ran my 2ch Triple with the gain the same way, so this could be one of the main differences between early 3 channels and later ones (pre multiwatt)

I lost all of my pics in an HDD crash so I'm going off my experience with all 3 amps.


I'm back to being intrigued about the gain pot values. I have a Rev E on loan right now, serial number right around the R-040000 mark. The gain seems on par with the Rev C+ I'm A/B-ing with at the moment, which should have 250k pots. It's funny to think they would change the pot values within the same revision (Rev E) at some point. Sounds like it would have happened within the last 8000 - 10000 tops.

Is there anyone that can confirm they have (or confirm the serial of one they've had) that's a late 3 channel (non-multi watt) Recto with 100k gain pots instead of 250k?

I just picked up R-17433. It's a rev C+. TM on the front logo. No brackets or active loop lettering. Hopefully this adds to your info! Let me know if there any other specifics I can gather off the amp.

Awesome! I think I saw that one when I was looking around... :mrgreen: I think you now have the earliest confirmed Rev C+, so that narrows down the serial numbers some!

I've been flipping a lot of these to document and test, and I still have a Triple at the moment that's a few hundred higher than yours. I don't recall the serial off the top of my head, but it's R-017880 or so. Somewhere in that range. Anyway, that one still has the 561140 PT in it, so I would assume that your does as well?

Yes, it does have the 561140 PT.

It's been a few years since I have had a rectifier (had a few tremoverbs in the past), so I was looking to get a 2-channel to fill the need. I saw the discussion about these early 3-channels being so different and was intrigued. I haven't had much time to play the amp, but my first impression has been that this is indeed different than the typical fizzy stereotype the later rectifiers get. Thanks for fueling my amp junkie tendencies :mrgreen:
