pass aleph 2

[Michele]

I'm interesting in a pair of Aleph 2, is someone able to tell me if they can be converted to 220V?

Thanks

Yes they can. Be sure to halve the fuse value also

matching mosfets

I am trying to convert an aleph5 to an aleph2.
I had a question about matching the output mosfets. Do I need to have the ccs and gain devices matched for a channel? For an aleph2 that would be 12 of them. Or can I match the ccs and gain devices separately. Two matched sets of 6 per channel. My understanding was that only the devices in parallel need to be matched.
I had used matched sets of 6 per channel for the Aleph 5 and I am trying to see if I can reuse these.

thanks

group of upper matched

group of lower matched

no need for matching between groups
