I understand that On Semi transistors are easier to get for guys in Vancouver area. The old favourites like MPSA 56 for BC 556 and MPSA 06 for BC 546 are drop - in replacements here but have reversed pins like 2N 5401/5551.
I hope this is of some help too.

Haha, You are correct, I do try to go slowly as not to make mistakes. Mix that will how busy my life is and my low funds. I'm also working on a danzup's source selector extravaganza.

Just a small update, I picked up my enclosure today. It's an 33cm-25cm-7.6cm rectangle, I'm not quite sure what its made out of... sheet metal maybe? I'll post some pictures when I have something mildly completed

Thanks,
Kurtis

Default Very good Meanman.... have you listened?

Post your evaluation for us as soon as you listen.

It is looking good, despite the big resistances.

The input condenser should not be bigger than 10uf..... increasing it is not increasing bass, the result is reduction of treble.

The amplifier, the Blame ES, is a little bit shy in the low end....the Blame ST, the last version, has much more bass.

regards,

Carlos
