Well done then Wayne, Stereophile should be getting the simple things - like who actually designed the product correct in the first instance.

The actual review has the correct info but is incorrect in the "Product of the Year" blurb.

The stereo version of this board is done and the gerbers off to 6L6. It can be built SE stereo with one board and balanced stereo with two. The silk screen is a bit tight but has all the needed information.

Some pics of the Prototype Purple Pre board in the wild—stuffed and bare—I was fortunate enough to be a guinea pig (SMD parts!! F U N.)... The DIY Store version will be DIYAudio Blue, silkscreen a little different I understand.

Waiting on a chassis (enroute) and I'm ready to wire it up. Thanks Jim and Wayne!

The silk now has labels for inputs and outputs on the connectors.

I still have the two small pink PCBs and for a long time I have considered building preamp mono blocks (two separate chassis) and use a mono volumen pot in each. Also for the headphone output I would mount a mono jack. Doing this I could get 100% channel separation for the headphones but will require I build two mono jack cables for my headphone. I have never seen a preamp built as two mono blocks…...probably because it is not practical with two mono vol. pots etc.?

Something Passlab has considered or has done?
Think it could look "cool"......

There were quite a few, although not common

Burmester did a double mono pre, and some others.

Downside is cost and complexity obviously, but apart from the tranny quite a few pres are double mono

Have fun

Claude

Hello MEPER,


there have been a few DUAL MONO PREAMPS. But with `dual-mono-pricetags'!



- GRYPHON BEL CANTO preamp


- PASS XS Preamp (in two cases: two completely seperated preamp boards `sandwich` - in one case / other case PSU)



for example.
