Default B1 in an Onkyo 2nd attempt...

I built this B1 into an old Onkyo case. There is a Goldpoint stepped attenuator in the Recording Level location and the power switch is functional as well.

I used a Sanyo case -- took contact cement and some aluminum flashing to veneer a new front to it -- this is a good technique for repurposing Japanese stuff. I use a Bessler roller knife to cut the veneer. Have also used black formica.

I didn't take any pics of the interior... maybe someday when I'm rearranging stuff again. Not much to see anyway... the standard board sourced from Pass mounted sideways down at the attenuator end. I hard wired from the Goldpoint (25K mini-V) to the board. Power comes in at the back on the opposite end and then through the power switch that was already mounted in the Onkyo. I feed it the 18V DC from an old Panasonic wall wart supply for a cordless phone... the Panasonic provides a spot on 18V with no ripple. I bypassed (jumped) the selector switch to simplify the signal path. It sounds marvelous.

Wouldn't it be better to place the trafo a bit further away from the inputs? It seems to be enough clearance. I love the attenuator, by the way is it a Shallco?

Regards,
