EAR Gristleizer Desktop Build Guide

Post by chvad » Mon Apr 27, 2020 2:23 pm

Anyone have one of these that they wouldn't mind sharing? I bought the old desktop kit a while back and while I have some downtime I finally want to build it but as fate would have it.. i have all the parts but no build guide and the link on their website is kaput. Thanks!

Gah.. turns out thats for a different/newer it seems, revisions. My PCB looks like this. SO I guess I'm looking for a revision 2 instruction set as there seems to be some pretty big differences between the two.

Can I jump in and request the guide too please?
I have one that has been in progress too long, thought the half built kit was in storage but I found it yesterday behind my desk.
Build guide is in the offsite storage and I have a bit of time right now to finish it. Nasty feeling that the power supply is there too, now I think about it, but could finish the build anyway.

Thanks in advance.

not that it's a contest, but i think i win for oldest PCB version:

anybody have th docs? component numbering follows the original Practical Electronics numbering as far as it goes, but there's a 6th IC and associated parts on the PCB that aren't in the original schematic.

Sorry for the Necro - I just came across two PCBs in my stash, I'm looking for the Rev 2 'Modular' build docs as well! I think I ordered parts at some point because those switches are unique.

Question for anyone who bought the TT PCB sans components and had to source them.... the BOM lists values for the components (Kohms or uF), but no other specifics. I'm trying to build a list in mouser, but with thousands of choices, how do you know if the one you choose is correct. The resistors aren't too hard to pin down, but the capacitors have voltage, temperature, ripple current and tolerance ratings.

This is my first time sourcing parts without a full kit, so I appreciate any advice or help.

You just gotta poke around ;)

Check the COMMONLY ASKED QUESTIONS link at the top of the DIY Forum homepage. There is a wealth of info on sourcing parts.

For Capacitors:
viewtopic.php?t=82443

25V caps are fine for this build, and you don't need anything fancy. It helps to match the lead spacing to the holes on the pcb.

Thanks for the help. That thread on capacitors was helpful. The others not so much. What I'm struggling with is the rotary switch and potentiometers. Trying to find ones of the same height so they all line up with the front panel. The build guide shows the pots with long right angle leads that bring it up to the height of the switch.

Rotary Switch

Pots
https://www.taydaelectronics.com/b100k- ... unt-l.html

https://www.taydaelectronics.com/p2-10k ... mount.html

I think I had had to fiddle with the legs on the pots a little bit to make them work. Nothing crazy, they are just a little too short to have the wider part if the leg sit directly on the pcb, but the pin will go through the hole. Solder switch to pcb, then mount switch and pots to front panel before soldering to ensure they are lined up correctly. Sorry about the fuzzy memory, it's been a few years since I built this.

Thank you. I found the 100k pot on Mouser, but not the 10k. Slightly annoying, but oh well.
