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

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

I would bet that that wooden board might have some sort of tonal effect, simply because the grain structure may conduct micro currents in a different way than pcb. Could be that such an effect might be even more pronounced in humid conditions. Though I suppose this is all dependent upon how the wood for the board has been treated.

definitely not--but snake oil certainly sells in this industry

how you feeling about the Hiwatt, now that the build honeymoon is over?

Sorry Jeff, I didn't see that the first time around. I really really like it man. With both master volumes (pre and post PI) that thing is insanely versatile and an amazing practice amp for lower volumes. I'M really impressed. It is, however, quite a bright beast and it sounded quite harsh at first. Being in "build mode", I got kind of a tunnel-vision thing and started thinking of ways to get it a tad darker by switching these, adding that, etc. etc. Still, I wanted to try a 12ay7 in v1 (bought a few nice NOS ones since I was building the 5e3) and put it in there. Sounded much better but I kinda missed the tightness the 12ax7 had. Put a "nice" 12ax7 in there (current prod Tung-Sol) and BAM! Smoother, a bit less harsh, amazing. Still debating which one I like best but it was a nice improvement (duh).

I said tunnel-vision because if it were anytime before I started building amps, my first reaction would've been to ditch the cheap chinese tubes that came with the kit and put some nice ones in there (my 2 favorite being TS and EH, they're really nice for current production). Still, since I was building my only reaction was to tweak the circuit... just shows how you have to take a step back sometimes.

TO: thank you again!

Demanic: I'm afraid I know of no species of wood that's known for having any electrical conductivity or even properties whatsoever so color me profoundly skeptical of this...

Y'all stay tuned for next-week's progress ya hear?
 
Re: New Amp build (5e3), from scratch...

So it's done, up and working pretty darn fine!

I've got a nice NOS 12ay7 in V1, a current prod TS in v2, JJs 6v6 and Jj in the rectifier as well.

Pretty sweet sounding and surprisingly loud for such a small beast. I'll be building the cab in the next few weeks.

Here are a few pics:

Yes, normally oven dried wood is an insulator. However, I qualified my remark by saying "micro currents" and "relative humidity". Which is to say that while the effect on tone may be negligible for the most part, exposure to humidity (depending upon how much and for how long) could indeed produce some sort of change in this, albeit slight.

Thank you gentlemen, I knew I could count on you two for a little huzzah... ;)
