12AU7 Starving Student Custom PCB Drawing - Critique Please - Page 2

Ah, very nice. I actually thought about using the modder's mesh on top & bottom like your configuration too but I was afraid of dust settling through the holes over time. I'm sure a bit of dust wouldn't harm it but I'm paranoid about keeping the internals clean without too much maintenance.

Anyone else with a home built wood/mesh case combo please post yours. I'd love to see what other creative designs are out there!

I have not calculated the total cost for one unit because I plan on getting enough parts to build two of these puppies. One for home use and one for at work.

But I am guessing that the total for one entire unit will be around ~$70. Of course since I have all the tools needed I am only counting parts and materials.

Thanks for the compliments. I have already reconfigured the pcb layout a while back but wanted to hold back on posting it. The reason being that I redid the layout 10+ times that I was still not satisfied, almost went crazy and I ended up building it very close to Dsavitsk's 19j6 pcb design. So I can't take any credit for just modifying it for the 12au7 tubes.

Anyway, here it goes! (Same layout used in 3d model) I plan on getting started on production in about a week when I get back from vacation. In the mean time, I would appreciate if you guys can double check the correctness for me :)

Not yet, I was on vacation all last week, and on top of that I caught a cold/flu while I was in Key West. I am recovering now though, and have ordered parts from mouser. There are a couple things I need to find at my local electronics shops but once I get those parts I'll start working on the pcb

Alright guys, I am very close to starting production on this amp. Here's what the pcb will pretty much look like.

I am still waiting on my mouser parts to come in the mail (should have been delivered yesterday.... not sure where my package is!). Also still missing some parts that was not available via mouser so I'll try to hunt them down locally.

Comments welcome.

Sorry, to clarify, when I said 'production' I meant I will be etching the pcb myself. I don't plan on sending this design to a pcb house to get made.

Although anyone is welcome to take this design and etch their own if desired.

Thanks so much!

 

PS. What is the BOM? Can you link me?

 

Heya,

You can find the BOM on Doug and Tom's website here: http://www.diyforums.org/SSMH/SSMHbom.php (with the addition of x2 390K resistors for R2/R8 on the schematic)

I don't remember where I found Doug's 12AU7 schematic but do a quick google search to find it.
