Hi Joe I have finished my two 99v BA's and my 1290, all looking good. Thanks again for all your help, apologies for bombarding you with all these beginner queries, I can only hope my lengthy posts will help other learners in the future! My next build is my 312-styled BA. Specs as follows: EA2622 inp...

Hi Joe I am planning to use some VU buffer kits and your small round 34mm meters on a 1290 build and a BA 312-style build. I am using the 40w 48v PSU. (shared between these two pres and a couple of BA's) I see the buffer kit can run on 9v-30v. What is the best way to reduce the voltage supplied to t...

No Worries Joe,

I'll grab one here.

Thanks again.

Thanks for putting my mind at ease again Joe.

Just remembered, one other thing: There was no 820R (for the stepped gain switch) included in my kit, but I received one spare 470R, is this telling me something or should I pop down to Jaycar for the 820R...

Thanks again

Hi Joe & Co. I started building my 1290 Macro today...A few things I'm not sure about: 1. Which way round does the 180pF plastic cap in the top left corner next to the relay go? The cap has one long leg so I'm assuming it is polarized...? Long leg on the PCB edge or towards rotary switch? 2. Does th...

Man, that was quick!

Thanks for putting my mind at ease Joe, Happy Camper.

Now on to the 1290 and my 312-style BA!!! Hoorah!

Hi Joe & Co. I have nearly finished building my two BA's 99v with JLM14 inputs, FET DI, variable Z and JLM111 out. (40w 48v PSU). I really enjoyed the process, a great way to learn! I think I'll be investing in a couple more BA's to fill my rack sooner than I thought! :D I think I got everything rig...

Hi Joe Many thanks for your reply. 2. Is it possible to put some sort of output trim pot/fader on a BA without adversely affecting the sound? (as on the 1290 and Dual99v) if so how? You can run a 1k pot on the output of the BA but turning down the output will reduce headroom and increases output imp...

Hi DIYers Having read the majority of the massive JLM Baby Animal thread over at GroupDIY and loads of others on JLM pre's I understand that some of what I am asking has been, in part, covered elsewhere but I thought a fresh take might help other newcomers. I have been spending a lot of time researc...
