RCA RC-30 vacuum tube data manual reprint, this is a larger, later (ca 1975) version of the venerable RCA manual that not only covers recieving types but many industrial numbers not covered in earlier editions, so it's about twice as thick as the earlier RC-19. Includes nearly all tubes used in US made audio & guitar amps. Also has useful Resistance Coupled Amplifier charts, and sample circuits. |
