I need some ideas regarding Fireproofing a new guitar amp I am making.
Its a guitar amp 'head' so it needs to be covered, but this thing is going to generate insane amounts of heat.
The front will be a laser cut metal grill so you can easily see all the tubes, and provide good natural airflow.
Any ideas on how I should make the case (not the chassis, that will be steel). What material, and what I should do for cooling?
Anyway I can do it in wood (outside covered in tolex), and somehow fireproof it. I don't like the idea of forced cooling tubes with a fan. Maybe a couple of extractor fans at the top, or 2 large vent holes for chimney effect.
I am still designing the amp, but this is why it will need fireproofing:
PSE 6c33c (2 tubes)
2 parallel 5C8S for the rectifier
Pre-amp at least 4 tubes in this section, 12ax7, 12au7... still working on this section, not sure how it is going to work yet.
Pre-amp will be powered by a separate rectifier, either 274B or a mercury rectifiers: 866A or 355A or 354A or 866Jr (but heard bad things about them concerning safety, and may not be a good idea in a portable guitar amp)
Also I want to try and stick in 2 OD3 voltage regulator tubes for the hell of it
