I built 511B in wood. Excellent result, wood horn is warm and sweet. Far better than other altec metal horns.

Audio system:

Klipschorn

Altec 511B in wood as midhorn

tweeter modified using EV DH3

audio amps:

1.2 W SE DHT amp using RCA 10 output tubes, 71A driver and preamp using RCA tube 26

1.5 W SE DHT integrated with RCA tube 26 and tube 45 as output tube

1.5 W SE integrated with 12AX7 (tube rolling with Telefunken, mullard and bugle boy amperex) and tube 45 switcable to 2A3 as output tube

CD Player
