New Amp build (5e3), from scratch...

Re: New Amp build (5e3), from scratch...

Got a bit of work done today:

Solid oak turret board (stained):

Pretty much all the PT wiring and most of the OT as well:

Thanks GS, here it is 90% populated (missing a few resistors that are in the mail).

Looks great. As I know nothing about circuitry, can you explain the way a turret board works? Is everything in series, and the signal goes from post to post? How is it different from a pcb board/bread board? Is this considered point to point, and why/why not?

Thanks in advance.

Edit: this is the inside to my Studio 2 (my favourite amplifier). How is Jeff's turret board different from yours? How would you rate this workmanship?

Well, the board itself (whatever is used) is nothing more than a physical support for the turrets, which are just electrically conductive terminals. They are not connected between them, unless you do so with a link (wire, usually underneath the board) or via the components themselves.
On the other end of this is a PCB, which is a board that is designed, via copper traces, to link components together, which usually yields a more compact and, IMHO, resistant build (if done correctly) as there's very little room for components to move. Note that many will argue the merits of all building technique and medium, I'm not gonna start on that subject.

Point to point would be the same basic thing but without any terminals or support, just the components linked directly to each other.

On your amp I see two PCBs (small ones on top) and two turret boards (lower bigger two). The turret boards are basically the same as mine, the main difference being the material used, I used wood for mine, this looks like regular nice fiberglass. Both fine choices.

Man, I'm not the man to ask about judging other folks work. I'm still very much a novice. As with pedals, the relative quality of a build will only be determined by what quality one expects or one's skill level.

On some boards this amp would be considered "OK" at best as I've seen guys nitpick some details that you and I would never ever consider relevant or even noticeable.

Still, you're asking me and I'll say this: If I could build something that fine, I'd be damned proud of myself. This is an amazing amp right there and, to me, the workmanship seems/looks awesome. I love braided wires and there are very few stray wires, everything's laid out neatly and there's lot of "empty" space.

Thanks for the thorough reply! I am now that much smarter! :)

Taking information from me doesn't make one smarter, that would imply that I am smart.
However, I'm glad I could help. :)
 
Re: New Amp build (5e3), from scratch...

looks great! very very few amps are actually point to point. most of the time when someone says that they mean handwired rather than pc board
 
Re: New Amp build (5e3), from scratch...

Aw you're at it again :D
Looks really good!
Hope the funfactor is high!!!
Like the fish :D

Yeah, I think I'm a lost cause... ;)
Thank you for the compliment my friend.
Fun factor is quite high indeed. It's another level for me, another step you know, just gathering and planning some more since this is not a kit. It's not like I'm designing the circuit but I'm not receiving a bunch of parts and then just put them together, I had to do a bit more research and all.
It's the Learning process that makes it so much fun.

You wanna know what's the saddest thing? I'm already planning the next one in my head...
 
Re: New Amp build (5e3), from scratch...

Haha....and while having fun you are learning all kinds of useful stuff!
What is on the list after this baby??

Yeah, as long as I'm Learning I'm enjoying myself.

Next? I'm tempted to make a nice compact 18w marshallish head (tweaked to my liking of course) or go completely bonkers and do a SLO-type build.

It's getting crazy: my 2203 with a PPIMV added makes me want to get rid of my Oranges (I love the TV50 and the Rocker but that 2203 is really killer and the PPIMV really gets the home-volume very convincing and great sounding) and I'm thinking a SLO might make me want to sell my Rectoverb...

I've been playing the amps I built much more than the ones I bought lately... scary...
 
Re: New Amp build (5e3), from scratch...

Over a week of inactivity...this really bites. Waiting on like 3 parts to come in the mail...damn.
 
Re: New Amp build (5e3), from scratch...

looking good.

how you feeling about the Hiwatt, now that the build honeymoon is over?
 
Re: New Amp build (5e3), from scratch...

Finally! My last parts package took more than 2 and a half weeks more than usual to arrive, which meant a big downtime on the build.

I've got two big shows coming this week-end so I spend my time getting ready but I still took half an hour to finish the turret-board tonight.

Here it is.

Expect more developments next week.
