This amp & cab combo appear to have seen a good many gigs, and have a great vintage look to them. The harmonic tremolo is on full display here, and sound great. It has OEM transformers from a Blackface era Bandmaster, dated '66 and '67 respectively. The choke is still original from 1961. Internally, it has the power cord and electrolytic caps replaced, along with some power resistors. A few of the original yellow Astrons were replaced, for the sake of servicing functionality (likely is why the trem sounds so good). Otherwise pretty much everything else is still original, including the stock carbon comp resistors in the preamp. See pictures for further details.
