Hi alex,
chassis is powder coated in antique finish as they called!
Thanks, I am exploring different kind of coating for my diy amp.
A1 Plating can do satin black anodizing for PHP850 for a 12"X15" aluminum plate chassis. Or I can just retain the "quite good" polished surface that I did and spray it with automotive urethane clear coat. (I might do the latter so i can claime a true "DIY Amp").
BTW, I removed the pot on my diy amp so I will be forced to diy a preamp. Am looking into the foreplay 3 or a 12b4 preamp.
Is the 6sn7 preamp pictured on this thread another of your diy preamps?
Your foreplay 3 looks gorgeous!
