Has anyone got the physical pcb layout dimensions for Din41612 type 'D' plugs/sockets as it seems that this is top secret and hence I can't find it anywhere, even from the manufactures themselves!

Thanks for the reply, but maybe it's not as simple as I made out. Firstly, I actually need two alternating pwm outputs with deadtime to run a half-bridge driver. The fastest PIC will only run at 10MHz (instruction cycle). Two PWMs@1MHz and deadtime will only give me a PWM adjustment of 50 or 40%...

Has anyone got a schematic of a simple but stable 5V 1MHz PWM oscillator.

Thanks, I will try and dig up what I can with the info supplied. Meanwhile if you do here anything else about the subject, please let me know. The more info the better by the looks of things! pc1-Engineer-Ultrasonics

Hi,you say you are using ultrasonics to clean your tubes. Two points here: 1.Ultrasonics do not work very well in flowing fluid,it kills the cavitation process, so make sure the tube is full of fluid, then ultrasonic it. 2.Have you got the right fluid?.Standard ultrasonic cleaning fluid will not...

Has anyone got or know where I can get information on megasonic cleaning, preferably types of circuit needed to run at these high frequencies. Any help would be appreciated. Many thanks, pc1.
