The RedRoo SE tube amp now has a chassis kit. Quite a few have been built here in Oz, but the chassis has always been a problem. This one uses extra thick FR4 panels which are silk screened and precision drilled by the PC Board manufacturer. It's a great way to make a good looking chassis at reasonably low cost 🙂

Just an update for those who are interested ....... I've updated the RedRoo DIY information to specify the 12AT7EH tube from Electro-harmonix. The reason for this is that the EH version has a heater-cathode voltage specification of 200V which is better for the cathode follower stage. Other manufacturers mostly specify 90V h/k.
Not sure if there is any real difference between the manufacturers, or if its just the way they specify it. I have seen various thoughts about this, but best to be sure.
(Increasing R11 to reduce the B+ voltage on V1 to about 200V would achieve the same thing)
