Oooo yes it is the custom. CRS vs CRS my mistake

CRS v3 built in 2011 s/n 44. Someone posted this on the two rock Facebook fan page last night. Hope this helps some.

I think this is very cool!! Thanks for posting! Trey has a big following for those who follow his stuff so I appreciate it.

I successfully recreated my circuit in LTSpice for further study. Sharing here for anyone that's interested in tweaking the circuit. One thing I might amend in this circuit is using 10KA send and 10KA return pots. Or at least a 10KA on the return instead of 1M I currently have. If you've already mad...

What do you mean by the ltspice files? The ones containing the designs, but also files with the tube models, parts, transformer models. Looks like I should just make a post here on this forum with all files I use, for others to use too and hopefully improve. I for one would love this, having just g...

Looking good!!!

Hey Ryan, the boards arrived today and look really good. The faceplate is also a very nice touch too. I wanted to lacquer it to protect the screen print but was afraid of dissolving it so covered with clear adhesive plastic instead. EDIT: the clear plastic looked bad so I hit it with clear nitro, i...

Yes, sorry for the delay. Heads down on the accompanying documentation. Based on my calculations, the 1m bias resistors are good to go. I have them in my prototype and it's very stable. The bias for the opa2134 is in the pico-amps so not much needed if you're using that chip. I'm using OPA2134, wha...

Excellent, thanks. Let us know if you are going to bias the op amp as suggested. I know it's only the v1 BOM, but I don't think the Mouser project link is the correct one yet. Is it possible to see a photo of the loaded DC -DC board with the inductors and Traco in place ? Good catch. Just updated t...

The BB should be good still. You just need to remove the bottom nut on your footswitch. I'm building my next one in a BB size Excellent, thanks.

Ryan what are those knobs? I'm going to the knob shop on Tuesday and like to get some similar cool ones :D Also if you do have a copy of the basic K-lator schematic, that would be appreciated, it used to be on Brown Note but is long gone, I think. Here ya go for the v1 BOM. I will add 2x 470k resis...

Impressive work! 8) I just wonder whether the lack of a bias resistor at the + input of the opamp may cause problems. See e.g. https://www.physicsforums.com/threads/voltage-follower-bias-current-opamp.788018/ or https://northcoastsynthesis.com/news/one-minute-op-amp-analysis/ Fair point! Thanks for...

This looks amazing Ryan, astonishing how fast you developed such a nice product. Even Dumble approved fonts on the PCB's. With a TL062 this would probably even run of a battery. I'm curious to see how the frequency response of the loop is and how well it works with long cables. Thanks! Here are som...
