An obscure Canadian literary reference in the build thread title seems the only thing straightforward about my latest build: 5F11 Vibrolux in a Mojotone chassis First efforts were stymied by a FedEx parcel thief, but Mojotone came through with a major assist and replaced the package. Now I've managed to get most of the board and chassis components and wiring done to find that my Hammond 290CAX transformer lacks the 5F11's 50V bias tap. Urgh. Can't blame anyone else for that mistake. Still ... , perhaps a question only the truly ignorant seldom-poster might ask the learned minds of this forum ... is there anywhere to steal the 50V bias tap elsewhere in the circuit? Or do I just need to suck it up and buy the Hammond 291MZ?
