Second photo with a vintage Pentax K10D

Here's a follow up to yesterday's First photo with a vintage Pentax K10D.

I haven't done photos of tubes & amplifiers in a while, but got inspired dusting off the cover my Leben.

Lens is a Pentax HD DA 35mm f/2.8 Macro, but for some reason this doesn't get parsed into the exif by the camera.

A good amplifier makes you want to listen to more music - and rediscover things. The K10D does something similar to me - re-experiencing and re-taking of photos of the same places and objects.
Visible are: Three transformers, one 6CJ3 tube, 4 6CS7 tubes (the smaller tubes) & 4 6P3S-E (Russian equivalent to the American 5881 & 6L6(GC) type of tube, the bigger/bulkier ones.
