Firstly, nicely exposed/processed image. Secondly, and possibly more importantly, ... film ... vacuum tube ... seems you're going back in time. What's next ... sliced bread? ... the wheel?
The above shot was taken with the 42mp Sony a7R3 and consists of 4 images focus stacked. Then painstakingly "spotted" in post to get it as clean as possible.
I've used tube amplifiers longer than I've shot film in cameras.
I'm cooking tonight over a fire in the backyard started with a piece of flint...
I only have one tube amp left these days. While I've had several over the years, I don't think that I've ever had more than one at any given time (unlike the guitars which just seemed to multiply like rabbits).
