After all of the trials and tribulations of my research then fruitless search for my next amp, I got a break. From mythical south-central Texas - and home of the Schlitterbahn - came a mint condition Super Dallas. Better than that, payment was sent on Thursday and despite the holiday shipping nightmare, it arrived yesterday! So, in the course of half of a week I found and took possession of the next amp. For me, that's somewhat miraculous.
