Default Valkyrie.... line-stage preamp..... info??

Anyone have links for this preamp?
I have built Jung's AD744/AD811 circuit found on his pages, but I wonder how this Valkyrie differs ?
The only info I've found is to order backissues from AudioXpress.
It was a project published there.

Valkyrie. A line-stage preamplifier. Utilizes high-performance op amps in the signal path. Provides a modest voltage gain of about 5 (14dB), but can be increased.

Default Valkyrie

It is the essentially the same circuit. The Valkyrie adds buffers to the tape outputs etc and is not dual mono.
