The tech diy kit uses one 50ohm instead of two 100 in parallel - thats why you don't see a R7 on the list.
Yes you can bridge them, but perhaps it is best to build them first and then bridge them afterwards. You'll need balanced inputs to get more power.

cviller, can you point me to a part # that will work on your diode pcb's for the heatsinks?
Need to put these black beasties to work.

You can get the right heatsink at mouser. Here is the illusive rectifier thread:

Tea-Bag,
You'll find that those boards make for a Dead quiet power supply! Use the snubber option and Ultra fast diodes you'll virtually eliminate any "ringing".
Make sure to use some type of mounting device (bolt or clip) to secure the diode to the Heat sink or you'll hear about it from Christian!!!

I'm glad I did.

Beautiful boards!

Hi, I am very very new to DIY AUDIO, could you please explane how I can purchase two amp PCBs and two Power Supply PCBs

Regards

Christian , I need to order rectifier boards and plan to use the snubber option , do you list the values for the snubber.

cviller · 16th March 2010, 05:55 AM

Last time I did some reading about it, 100 ohm and 22-100nf appeared to be what most people were using. But if you want to find the best value, you need to measure with a scope or follow the guidelines specific to your diodes.
I have collected a few hints in this thread: Gb: Rectifier boards

Hi esprit, you can order from me at my order site: GB order page for cviller you might also want to check out my blog (in my signature), where I'm trying to collect information as a guide to f5 builders.
