I´m scetching up a layout for a tube based preamp. I would like to use a low profile enclosure with the tubes inside. But if the tubes are standing up lots of vertical space is needed.
If the tubes are soldered directly to the pcb i could get away with 75mm internal enclosure height:
15mm space between bottom plate and pcb
2mm pcb thickness
50mm tube soldered directly to pcb
3mm space to vented enclosure cover
70mm total
Using a tube socket on the pcb would increase the total height by approximately 15mm, and I don't like that.
The obvious drawback is that changing tubes is a hassle. But is there anything else?
