I'm using the BYV27's, but not with any snubber since I don't know how to calculate an RC-link.

The caps are: 2x2200uF Panasonic FC + 2x2200uF Vishay BC. Diodes are BYV27-150 soft recovery incl those protecting the LM317T. Fuse is 800mA slowblow. Electrolytes decoupled by one 0,22uF and one 0,1Uf for each cap except for the 10uF cap that's deoupled by a single 0,1uF. Decoupling and...

Done with it now except for casing. Bottom view: Side view: Other side, you can see the Supra LoRad 3x2,5 mainschord. Simple setup so I can listen, this is clearly one of the greatest improvements since I started modifying the Btech

Quick question, since there's no room in the box I bought anyway...would it be beneficial to put 2 Panasonic FC 470uF after the Panasonic FC 2200uF? Or would it be better to add two of my other low ESR 2200uF? Also I've heard a million times about the benefits of putting 0,1uF Wima's over the...

The resistor values seems to up the wall, I used an online calculator at : http://www.unisonus.com/projects/sim_supply.htm the values I got from that might not work in this circuit. Yes they will, nothing wrong with it, just me being stupid. R1 = 220ohm, R2 = 3Kohm gives 18,3V....I've...

Will this work? R1 = 220ohm, R2 = 2.2Kohm for +16Vdc Can I use MKT's for C-in and C-out , and an electrolytic for C-adj? What size does the resistors have to be? I've got 1/4W, 1W and 3W 1% metalfilm

Side view with the casing I'm not going to fit it in, have to find something else. Top view, crappy photo.

I have now soldered the transformer, diodes(UF4007) and 2 Panasonic FC 2200uF. Measured Voltage on the last cap(before I placed the bleeder that's in the picture), and I got +24Vdc without load. As you can see I haven't cut off the leads yet, wanted to test it first.

Forgot, I also have 1N4148 fast recovery diodes, and 1N5819 Schottky diodes.

error401: Thank, I'll look at that when my head isn't full of cotton due to a nasty flue. Still I've actually started soldering it today.

I think I've done all that I can on the BT928 itself, so now I'm building a stabilized PSU for it. Actually I'm thinking of giving the BT928 a bit more than 15V, maybe around 16-20V. Anyways this is what I've collected so far. Transformer 2x15V~ 20VA LM317T regulator Diodes: 1N4007...

Ok, thanks! =)

With the power on the secondarys at 25V~ MUR820IR should be fine right?

I have a little project going on the side that requires 32 pcs of MUR860 diodes, however I can't seem to find any here in Sweden... Does anyone know a good substitue for these that will fit a PCB made for MUR860's. Any help appreciated! /Mayday
