Completed TDR pics
« on: November 12, 2014, 03:16:09 pm »
Here's one for y'all...
I'm gonna miss this amp when it's gone because it has been the source of some good old fashioned amp-inspired playing recently....everytime I plugged into it, I would wind up playing for about a half hour before I even knew what happened.

The chassis, iron and sockets began their lives as a Judybox 1x12 combo that I picked up locally last year for $80,,,with some additional parts, supplies, etc., from a guy who was done with it all.
The guy who I built this for just wanted it in a head cab, so I used one of those 2 pine head cabs that I built last year because luckily, the chassis fit right in there....so no additional woodwork was needed.

I gutted the chassis except for the heater wiring, and replaced the stock OT.
The circuit is my take on Sluckey's Tweed Deluxe Reverb,,,with 90% just as he planned it and the other 10% my own interpretation. I was completely shocked by how much I loved the sound and feel of this amp, and I suggest that anyone considering a low wattage AB763'ish type, go right ahead and start ordering parts.

So, the guy wanted a blue LED back-lit face panel that would shine through his nick-name ( RHINOL )....he listed his tone references as Jerry Garcia and Trey A. and just said he wanted some clean, with a little grit at a lower output,,,and this is what I came up with. I used wooden letters on a clear Plexiglas background to get the shine-through effect, and I like it, unless I look at it too long and start picking out my mistakes. I used some Grateful Dead'y looking letters that I found at Michaels and just trimmed 'em top and bottom to fit the faceplate.

He's picking it up tonight, and as much as I will miss it,,,,I am looking forward to moving on to the next beast on the bench.
This was a low budget build that wouldn't pass my normal quality control,,,but I've got way too much time on it as is, so it'll just have to be......I learned some stuff.  :wink:

Nice stuff SG! Funny that you should mention the TDR. That's the amp I've been plinking on for about 3 weeks now. Still one of my most favorites. And just today I got a pm from a new member saying he has just completed one. AB763s and 6V6s are a nice combo.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Thank you Sir!
I can't agree more about this amp...
I play a little game here I like to call "Amp Wars" and this thing won 10 out of the last 10 matches....

It just figures that I enjoy it sooo much, but built it for someone else. :rolleyes:
But I am thrilled that it's getting off of my bench!!   :occasion14:
Here's a 'better' pic I snapped with my cell phone

Adds or subtracts the bypass cap from the first stage... :sleepy2:

Done deal.  Good stuff.  I know you will enjoy the AB763.

Yeahhhh man, CROSS IT OFF THE LIST!  :happy1:

The guy came to pick it up and stayed and played for about a half hour, and was really happy with it.
He's got a ton of pedals to put in front of it,,but still enjoyed the pure simplicity and sweet tone and reverb.

I removed the bypass cap from the reverb send triode to give him a better usable range on the pot....that seems to be my patented move.

Cool Amp SILVERGUN  :smiley:

only ..... RHINOL seems to be the name that a friend of mine could have given to an amp .......he is an apothecary

as is something that it is particularly suited if you have nose problems   :l2:

Sorry  :icon_biggrin:

No, really, nice amp  :thumbsup:

One notable move that I incorporated on this was to put the input V1 socket right near the input so I could have all short runs, and run the tone stack on a separate little board, right back to the volume control and right into the second stage all within that tight little area...
The chassis was already punched for 3 novals, so I had to put it somewhere,,and I thought this was kinda clever.

...probably got the idea from staring at some Soldano gutshots

Well, we found that you have not violated any copyrights, yours is RINOL not RINOIL



I would like to have all of your energy, each month a new amplifier  :notworthy:
