painting tubes black for heat disposal???
spamhog wrote:
Dull, black, heat resistant paints have been used to help cool engines for ages. It would be cool (literally) if one could spray and heat-cure unshielded tubes and improve their heat-shedding Is there any indication that such paints, or some vacuum-tube specific types, would help keeping tubes cool by improving heat radiation? No, but don't let that stop you from trying it anyway. -Chuck |
