Well, I know they're listed as substitutes. However, I'd like to be able to validate how close they are to each other. The data sheets I've seen aren't exactly the same for the two - even for a given manufacturer.

It's cool to find as much as possible substitutes :grin: So, I ask again (since I still don't have a schemo and don't have a clue about) is it possible to substitute 2N6107 with BD244B or BD244C ?

You won't find much at maplins for this project (and many others) !
Try farnell.com and rswww.com. These 2 suppliers will stock most bits you want such as resistors, caps semis etc. The BIG red wimas are at mouser or I think Volker said Conrad had them
Have you downloaded the parts lists from page 1? Most of the supplier codes are there
Hope this helps :thumb:

I'm looking at the curves for the 6BQ7 and the 6BC8, and it looks like they're somewhat different. You may have to play with the operating points to get it to work the way you want.

Will be nice if Analag can put that in the simulator :wink:

When I look carefully, they look similar enough to give it a try. It's kind of hard to tell exactly how close they'll be.
