I got lucky today at a local market and bought 5 tubes for $2 each including a 'ECC83-Telefunken-420', '12AU7-Made in Holland' (with an "M..." but all other letters worn off-a Miniwatt?), 'AWL-12AU7A-Japan' (NOS), '12AU7A-Made in Australia-WC23' and a 'Miniwatt-Made in Australia-12AU7A-262'. I had to sort through a box of about 300 tubes but it was worth it especially for the Telefunken. I haven't tried them in my Pro Junior yet as the amp is apart awaiting adjustable bias mod, new caps and resistors, but I'll be happy if even 2 out of the 5 tubes are useable. Anybody else score (tubes) lately?
