My first successful scratch build!

Post by gui_tarzan »

Finally! I have a working guitar amp that was hand-built by me. It still needs some tweaking but the damned thing works! After months of experimenting and trying different things (along with my regular amp repairs) I have what is mostly a tweed 1958 Fender Bassman 5F6A circuit. Now comes the tweaking and fitting with an appropriate speaker, and I have a true, hand-wired, point-to-point all-tube amp at a cost of pennies on the dollar.

Two characteristics of myself that I value is my persistence and determination and they finally paid off. :bigsmile:

No pics yet, but I will take some once it's done.

Hammond PT and OT out of a '60 M-100, JJ 6L6s, Shuguang 12AX7s and a handful of parts out of the parts box. Repairing amps is great and there is a lot of satisfaction in doing it but actually building one from scratch, point-to-point is even more gratifying. Hats off to you guys for encouraging and helping me these past months, it has paid off in spades.

:D

Now if I could play guitar as well as I can play bass I might actually have something. ;)

Ah, what the heck. Here it is, please excuse the mess. I'll clean up the wiring when I put it in its permanent home chassis.

Great job -looks killer!

I am a huge fan of point-to-point wiring. Not because I believe it has any sonic benefits, I just like how simple it looks

Congrats! Quite the thrill powering them up. Then there's the tweaking, closely followed by the thinking about the next one...

You'd think PTP build isn't the best approach for a 1st scratch build, but it turns out that it's a great idea. My 1st scratch build was also PTP -- a Franken-champ. I found that using the schematic like a layout was about the simplest approach and it worked out great after someone helped me find the 100K that should have been 1K!

Congratulations on a job well done!

Now, as Martin says, it's a slippery slope to the next one. You might as well cave in to the force and start accumulating parts.

Nice job!

It's funny when you do point to point, it doesn't look like that many components.
But put those same parts on a eyelet board and suddenly it's crowded. :D

gui_tarzan,
Please excuse and relieve a newb's confusion/curiosity. :?: How does that work out to being a 5F6A with only 2 12AX7's? Did you cascade V1a & V1b? I see that you provided 2 extra sockets for future experimentation.
Just Curious,
Gene

And, Oh Yeah,
Why go through all the hassle/aggravation/etc. to swap it to a different chassis? I think it looks great, as is and a nice set of face/rear panels will certainly disguise/cover a lot of sins! 8)
