I have a Grange running Psvane 300B (supplied by Mick as stock) Black chrome, previously had a Cabernet dual, with the jarra wood?, I personally liked the cab dual finish better.
The grange is a great amp, very quiet noise wise.
I had a few issues during shipping like the trafo in the power supply getting loose, I had to tightened the central bolt that holds it (not too much since you can deform the top plate), and had to mount the actual pre on 4 isoacoustics as the stock rubber feet tend to be short on length.
Aside of that great pre, congrats @deutscherhififan hope you enjoy it
I got the EML 45 XL tubes and I kind of prefer the 45 over all other 300B I tried but the psvane is actually very decent
My only big regret of which I was aware of is not being able to use MM on it
