An inexpensive audio transformer with DIY projects

I'm planning to have a small run of PCBs made for this one. etching and drilling each one myself, and then building them up is just too time consuming, and since there's three of them in this pedal in order to make it fit in a 1590B, it's hard for me to offer them for sale.
once I have the PCBs, it'll be a lot easier & faster and I could sell the pedal for a more reasonable price.

When they arrive, I'll definitely be interesting in hearing what the reasonable price for one is! :)

here's a couple of pics of the newest PCB's for it. i'm going to be testing this final layout version tomorrow.

I expect it to fit in a 1590B enclosure.

John, when planning how many PCBs to get made, count me in :)

I'd really really like to be able to say that I'm in as well, but for me it'll be a little more price dependent. :(

If you get an idea of what it'll cost John, maybe send me a PM (or post it here) and then I'll be able to say whether or not I'm a definitely "go" or not.

unfortunately no. i'm creating a gerber file for the PCBs now, but I won't have any others than the first one built up by then.
after that, i'll have to wait until the PCB's get here. I do have 3 more of the TY250P's though (I ordered four when they had 9 left in stock).

I won't know until it get a price on the cost of the 3 PCBs for it, and then calculate the cost of all of the components.

John, I was looking at your layouts and have a suggestion.... Keep R11 on your main PCB close to U1b. This will help prevent that stray pickup of noise that you were getting with the TL072, so it may benefit the 4558 also.

Ok, I'll go first with bringing up the issue of finding someone to build these... @DirtyDuke @Feral Feline , did either of you guys have any success with Hamish at Southampton (or anywhere in Canada :) ) around finding someone to build one of the GK Rails pedals? If so, perhaps they could build this one too?

I so badly wish I had some building skills right now. So. Badly.

I haven't approached Hamish for any custom build just yet myself, I merely suggested him as possibly willing to do a custom build.

Are you selling the Trio of PCBs, or just completed pedals?
