Hi,
The one we're doing, it's 100W type and there's no driver (12BH7). I think not all of them had the driver tube.
I am not sure if the filter is same between the 100 and 150W versions.
BUT, seeing how the filter is done, I guess that'd open it up for tweaks. having said that, I am not sure what else is different in the 150W version.
The release is almost there. We were screwed by a company which was supposed to supply us with the inductors. After not hearing for several weeks despite numerous emails and phone calls (this is to FL, USA), I had to ask my winder to make em for me, so thats in progress.
Well, the company did get back to me, a few days ago. The price was 5x more than originally quoted (MOQ was 1500 pcs by the way).
I wish this could have been done sooner, but no way we were going to agree to that.
In the meantime, while waiting for above to play out, I did add a mini switch or two for more tweakability to the amp!
Hopefully, we can get this released soon.
Thanks!
Nik
