Anybody here build a TWF? I have a pcb and I'm interested to see the part numbers on your BOM. Especially if you saved it at mouser.

I just got a board too..

is the one on here not right?

Yeah.. That's correct.

I was just curious if anybody had actual part numbers with affordable parts.
I've found that when I source parts I sometimes pay to much or buy parts that are wrong and then spend more "rebuying" the same stuff.

How do you plan to mount the pcb?

Thonk Support · Post by **Thonk Support** » Sat Feb 25, 2012 1:26 pm

not sure yet, but definitely as shallow as poss.. must be some pictures of other euro builds around

thedug · Post by **thedug** » Sat Feb 25, 2012 2:17 pm

One option is to make it wide and must mount the board directly parallel to the faceplate

Thonk Support · Post by **Thonk Support** » Sat Feb 25, 2012 3:27 pm

I might actually panel it together with something else.

My TWF PCB just arrived too.

Mounting parallel to the panel certainly makes sense.
Unfortunately, the PCB is just a few mm wide for a 14HP panel, which is why the production model is 15HP.

I plan to add attenuators to each of the Bias CV inputs.
This partly justifies bumping up the panel width a few HP to an even number.
Could maybe also add a 3-channel bi-polar mixer behind the same panel, or one of Negativspace's (2.0) Buchlidian Voltage Processor PCBs.
Any suggestions?

Thinking about laying out my panel in a downward cascade, the opposite of the Toppobrillo panel.
Also, putting the Bias 'All' CV and attenuator inputs, and Input 1B attenuator/Offset at the top.

Cool. Let me know what you decide to do.

Have you started sourcing parts yet? I put a list together and the parts came to $100. There must be some cheaper parts..

This is a custom build that i ordered from a wiggler here.

thedug · Post by **thedug** » Sat Feb 25, 2012 9:44 pm

Cool.. Who did you get that from?

PF · Post by PF » Sat Feb 25, 2012 9:49 pm

Its from Manhattan Analog

, wiggler Negativspace

, one of the best panels i seen of the TWF, its wider then orginal (18hp) but you have more control knobs.....

Here's the pics of my build... I decided to do a parallel-mount on this one just to see if I could. The brackets are all hand-cut from thin aluminum sheet, using heavy-duty kitchen scissors. (Extra high-tech, yo.) I'm not sure I'd recommend it... it looks sexy in pictures but the wiring under the PCB is thick, to say the least, and getting the brackets all made was a pain in my ass. Note the intricate system of washers used as spacers...

Edit: It wouldn't be hard to put holes for standoffs on the panel, I think. I just try to avoid that unless it's completely necessary.

All i can say is....

They are so good looking....

Thank you.

(I think I put ~45 hours into that design before I was happy with it. Easily the most time-consuming panel design I've ever done. Also one of the most expensive - $95 as-shown @ FPE.)

The Panel is worth every cent......

thedug · Post by **thedug** » Sun Feb 26, 2012 10:39 am

Here's what I ended up getting.

Note:

1) I opted not to get the headers for pots and jacks
2) I already have a bunch of jacks I got from here: http://erthenvar.com/
3) I couldn't find a non smd ferrite bead. Anybody have a part number?

I pmd toppo but I feel like i missed this batch. If any one has an extra they don't think they will use I would love to take it off your hands!

Thonk Support · Post by **Thonk Support** » Wed Mar 12, 2014 9:15 am

I'll have a new batch of TWF PCBs in stock at Thonk soon, 281 PCBs too.

Very interested to get one of these!
Is there a Euro panel in the works ?

bookends · Post by **bookends** » Wed Mar 12, 2014 11:55 am

I have a TWF PCB I'll sell if someone's interested. PM me

I too would love a panel for this if anyone is considering making one?
