Well the Valab arrived and has been duly fitted.

This one is far less noisy than my original - that might be because of its construction or its impedance.

So far so good - It does sound good but does it sound better than the ALPs.

Only time will tell.

I've just found a UK supplier of 2SK170BL at the silly price of 75p each with NO minimum order quantity.

electronic component suppliers and distributors, Nikko Electronics for semiconductors, transistors, capacitors all major brands of spare and replacement parts

I've just ordered 20 of them to get a few matches - those I dont need I will pass on.

Dalbani is on my list of preferred suppliers.
Some of their pricing is very competitive.
Their stock is large (huge).
Their customer service can be very good. I had a problem recently that was not quite resolved to my satisfaction, but maybe I'm a particularly difficult customer.

I use Cricklewood Electronics a lot too. Especially for some of the more obscure stuff.

Why was the MUR120 / MUR840 chosen for the DCB1 ?

I just happen to have a pile of BYW80-150. They look as though they will do the job just as well ?

Default BOM confusion DCB1

I'm just ordering the components that I dont have for my DCB1 trial.

I'm confused with the BOM.

On the schematic there are 4 x 47R resistors fitted between VCC+, VCC- and the Sources of the IRFP240 and IRFP9240.

They do not seem to appear on the BOM.

I can guess that they should be 1W each but then they would be too big to fit the board.

The BOM does show 4 x 470R 0.5W Carbon types. The only 470R resistors on the scematic are Gate drivers which surel;y don't need to be 0.5W.
