DIY Soldano type preamp

Re: DIY Soldano type preamp

Damn Rob, I been there, but not with an MSD, just a normal GM HEI, and THAT is around 35-50k volts, I think you might have hit with more, or t least a lot more times, they rebuild voltage quick (MSD = multiple spark discharge).

Those thing really fry your ass. That is a real waker upper.

Re: DIY Soldano type preamp

Cleveland Metal, i guess they are bringing the voltage up in the rocktron preamp to drive the tube. I can't imagine using 12V to supply the tube.
Yes i have 230V here coming out of the wall socket. However the power transformer i have is also easily wired for 110V use or anything between. Yet again that's the reason why there are so many cables around the transformer.

Well i don't know but i don't think those caps can store the voltage for weeks. I measured it after some minutes and it already was down. But normally i know where to touch and avoid the power supply section if i don't really have to.

If you want to get into DIY i think the best start is building a pedal. It's cheap, not to complicated and not as dangerous as a project involving tubes.

If you follow the link i posted above you get to the site of the guy who did all the design work. There is a link called "Belichtungsvorlage" where you can get the layout. However you need to make your own boards as those are only infos found on the page.
I already made about 30 of various boards in total and really it isn't rocket science.

Yes drilling can be a bit tricky but if you use a leveler for all the holes, a drill stand and good drills (just but a new set and it's a breeze with new drills) it's doable.

Also thanks for the nice words [img]/images/graemlins/toast.gif[/img]

Oh yeah, Ive been there many times on a standard GM HEI, but the MSD and Blaster coil made the stock HEI feel like a 9v battery on your tounge. [img]/images/graemlins/laugh.gif[/img]

As for drilling the holes in the board, you might be interested in a dremel drill press. They make neat little drill press' that hold in the dremel tool. Ive never used it on a PCB yet, but Id tend to think that it would work great!

Re: DIY Soldano type preamp

Well i have a dremel,although without a drill press . But i use a small drill stand (stands are mandatory for drilling pcbs as those very small drills WILL break if you don't use a stand) with an integrated drill press.

Well even with a drill stand i managed to break several drills. But overall it works quite good.

DUDE that looks awesome. what kind of time does a project like that take?

Re: DIY Soldano type preamp

Well this really depends. Provided you have all the parts, you are skilled and have enough experience with such projects and don't do any major mistakes i guess you can finish this project in one weekend.
However i normally need more time. Several weeks always go by before i am completing such a project. There are several reasons. Mostly i don't have much time from Monday til Friday so the weekend is normally building time. I always wait until i need parts for more then one project before i order them. Often i am missing some parts which i need to reorder and then i wait once again some time until i order because it's just not worth it to order only 5 resistors.
