Here is a valve phono amp using conventional circuitry design that is now surplus to requirements.

This is all triode, Mullard ECC83, plus CV? ECC81, then ECC82, with traditional mains transformer PSU.
In order to provide ventilation and to show the valves I opted for a perforated front panel.

Now has two blue LEDs to indicate power on:
