I'm in the process of gathering parts for this amp and see that Mark has closed his site, and things are rather quiet over at AK. So was curious if anyone here has been building or has any tweaks for this while I'm still researching. Have iron and chassis, along with a couple pairs of KT88's...older EH and a lightly used pair of PSVane that I grabbed off eBay for a nice price just to use for testing and start up while getting final ps values. Any thoughts welcome...thanks in advance.
