Zen Mod Napisano Maj 17, 2011 Autor Share #991 Napisano Maj 17, 2011 Hi ZM,I got my PCBs from "printed.cz" and am busy populating them.I do have a question, to start off...the zener diodes for output SEMI's protection do you advise their inclusion or not ?I'm not sure if i should put them in or not, although i did include them in the PCB redesign. Hi CVI agree with my Tweetie friend - they're must , for mentioned reasonsbut - you can omit them if you have variac , and you know what you're doing in every moment of first powering upI didn't had them even in prototyping stage , but I later include them on schm tnx to AR2 - who manage to scorche two semisouths , due to lazyness ........ didn't checked LEDs from drawer ( those for cascode biasing) ...... anyway - you can put them for start , and cut them from circuit later , when all settings is done Link to comment Podeli na ovim sajtovima More sharing options...

AR2 Napisano Jul 6, 2011 Share #1007 Napisano Jul 6, 2011 I later include them on schm tnx to AR2 - who manage to scorche two semisouths , due to lazyness ........ didn't checked LEDs from drawer ( those for cascode biasing) ...... Careful with that Axe Eugene! This is pure example of miss information. LEDs were purchased and not from my drawer. Diameter was not specified, if memory serves me well, just green ones. So I got the big ones instead of the smaller ones. It is possible that I am wrong on this but I remember thinking which ones to get, and that is the part of the process I hate the most... looking at million choices at Mouser catalog. As the result we were not able to set it up until we took two out. And yes, I guess that managed to burn two of the precious devices, my dear Eugene.

generg Napisano Jul 6, 2011 Share #1009 Napisano Jul 6, 2011 Bubba is right, I also bought first the big green ones and was astonished how many different choices I had, but after some scratching of my head I realized the Master Zen Mod liked in Pumpkin the little small green ones .... :connie_nutzo: .So I bought a new batch and had no trouble.... It is always good to know the habits of ones master.... Link to comment Podeli na ovim sajtovima More sharing options...
