Yeah, you could make a one-tube amp out of it. I'd suggest using the triode for the input stage (MANY guitar amps use that triode for their input stages) and the pentode as a single-ended output. There's not a lot of gain to be had, but it should be enough, if you leave out fancy tone controls. It won't be very loud. Or you could make a hybrid design, either using the triode as the input stage with a solid-state tone stack and driver, or have a solid-state input stage and use the triode as the driver for the output stage. Mullard offered a "Three Watt Economical Stereophonic Amplifer" using a single ECL86 (and a rectifier tube): http://www.r-type.org/articles/art-003g.htm It's popular for inexpensive, low tube count amps. Here's a guitar amp using one and a 12AX7: http://www.albertkreuzer.com/pics/el/ecl86/schem/recycle.gif There are even companies offering PC boards and kits to use this tube: http://www.dbevolution.it/ > Also, there's a guy here in my country selling the very same tube for ~13 > dollars US. Is it worth it? Might be - since this TV tube has audio applications, it doesn't have the low price and high availability of most TV tubes any more. If you want to build more things with 'em, you might use its less popular cognates with other heater voltages like PCL86/14GW8 and UCL86. If you enjoy building tube stuff, you might investigate the funwithtubes and Tube Collectors Association mailing lists as well (I'm on both). - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
