Lite ovanlig modell ändå. Blonde gjordes väl bara fram till 1963 tror jag. Och de hade prescense. Blackface kom 1964 men hade midpot. Spelar ju ingen roll bara den låter bra. Men alltid kul att veta vad det är för stärkare man har att göra med.

Men det verkar vara en 63a enligt gummistämpeln på "rörlappen".

Det här schemat tycker jag passar om jag inte missat något.

"Twentieth Century Guitar" http://www.tcguitar.com/articles/gagliano_pt2.html
"An example of a transitional amp is the first batch of blackface Dual Showmans (AA763). These are very rare and are prized more by collectors than players. The blackface Dual Showman circuit was introduced in September 1963. The amps were covered in smooth blond tolex and had tan/gold grill cloth. The very first batches of these amps (Prod. #2 for sure, but likely Prod. #1 as well) from September and October 1963 used a quad of 7355 power tubes instead of 6L6GCs as [used in] the blonde Dual Showman (6G14-A) and most blackface Dual Showman (AB763).
This amp uses a completely unique output transformer (Part # 125A18A) not found on any other amp though there is speculation and some evidence that a few of the very earliest Twin Reverbs used 7355s since, like the Dual Showman, it was an 80 watt, 4 power tube amp with a 4 ohm output transformer. In addition, the 1963 catalog specifically shows 7355 power tubes for the Twin, Showman and.... the Bassman and possibly the Concert! These days 7355s aren't too easy to find either. Hence, these are reasons why players don't care about these rarebirds very much and have converted some of them to use 6L6GCs… Debauchery!"
