[QUOTE="Ampdog, post: 34129, member: 144"] Just found this again. Yes, one can build one's own for far less than the commercial tube tester. If one is an audio fan, chances are you will only be interested in a few tubes - no need for the exquisite switching gear etc. of the general tester. I have done that: Sockets, one for ECCxx types, then ECF80 types, EF86, 6AU6 and power tubes almost exclusively just one socket (no switching). And an E182CC socket for myself. Large face meter, two power supply voltages (330/450V) and low current G2 voltage (100/250V), adjustable bias. If desired a meter back-off and push-switch for gm can be included - I did not do that. Infrequently a commercial type was on the market for around R450, but scarce. In my case I had most of the parts lying around. [/QUOTE]
