Monbrison Versions

[Truemaineiac]

Can anyone list the versions of the Monbrison? I know there was a no window, a window w a green power switch, window with rocker type switch, and an outlined window with conical type selector and volume knobs. What are the production dates for these and any technical differences? Am I missing any?

I think the only ones that can help on this is either Jonathan or Matt.

"... outlined window with conical type selector and volume knobs"

That is the current version...

I think the early ones were built all on both sides of a single board, and later ones built in "compartments" like the Masseto. That had to be a huge change.

In a way, each and every preamp is unique and special due to it's hand wired nature.

That being said, there have been 2 models specific to the US market over the years. The first model being imported into the US, was reviewed in 2004. This had an opaque faceplate, and different circuit than the current model - which has the popular 'tube window' on the front fascia.

Yes, it has gone through a few aesthetic evolutions over the years in regards to components changes, such as on/off switches, and knobs. Nothing that would change it's 'version' per se.

Thanks Matt, so just an aesthetic styling difference between window versions then if I understand correctly?
