Meet the PushOver
« on: October 21, 2014, 07:43:27 AM »
Hey guys! Here's yet another project I wanted to share with you. Got some tubes a couple weeks ago (4x 12AQ5's, 2x 6AQ5's, and 8x 6J6's) because I wanted to put some ideas I had a while ago into practice. One of them is in the following schematic:

It's a simple circuit that I wanna try out soon. Haven't had time to try it out yet, but I will get to it when I can. I also had a couple ideas for the chassis this amp could have, but I'm probably gonna do something completely different from them (I don't know where I could get either of them made, so I'll just do something else instead).

I'll update as go along.

[UPDATE]

Had an idea for a cabinet based around a 6" speaker. It's simple enough to adjust the dimensions of the box for any other speaker size tho, and could be used either for a cabinet or a combo.

If you say theory and practice don't agree you haven't applied enough theory.

Yes, I started experimenting with voltage multipliers after reading about those builds from ozvalveamps. However I prefer using only one P.T., because if I were to use more than one like they do, it would be the same price as just buying a transformer with B+ windings. They're not that cheap here in Brazil.

Now there is a man who understands the meaning of "compromise".   :lmao:
{If you only get yourself one thing for Xmas, make it a step-drill - when it comes to larger holes you'll  <3) it.}

Excellent improvisation  :dbtu:, but I'm curious, I feel I should recognise whatever that is that you used for a chassis even after you beat the living crap out of it, but I don't.  ???

If I haven't mentioned before, computer repair shops will generally give you all the dead power supplies you can carry, and apart from the wire and sundry bits, the cases themselves can be used, even bolted together, as tough project cases, e.g.;

I would love to get a stepper bit if they weren't 200 bucks a pop here in Brazil (at least I couldn't find any cheaper than that). Also they're very hard to find! I don't even think there's a single store that sells them in my town.

The chassis is made out of leftover gutters my dad found in the street. Just very thin (0,5mm?) aluminium, easy to work with.

I know about the whole computer PSU deal. We had bunchs of those cases lying around, but I have no idea where dad stored them, or if he got rid of them.
