Kris Boomer 2 small tube 10 meter linear amplifier 6ju6/6jb6/6jf6 tubes



Published
Quick video of another Kris I found in the back, in the corner, in the dark. This is a Kris Boomer. Uses 2 small 9 pin 6ju6 tubes. Same base as its big brother, the 6lq6 and family, but about 1/2 the output. It looks nice, this one is in good shape, has good original 6ju6 tubes and does what its supposed to which is 50 RMS / 100 peak.
As far as amps go, this is about as simplistic a design you will ever find. Grounded grid tubes, basic full wave bridge power supply turned on only when transmitting by the relay, Pi output circuit, no tuned input circuit, no preamp, no meter, but it does have an output indicator light. I do like modulator type amps, which this is not, but other than that, I like this no frills design. IMHO pretty much all preamps in amps are junk anyway. Here is the schematic on CBTricks and even if you are no tech at all, you can see that there is not much to this amp. http://www.cbtricks.com/Amp/kris/boomer/graphics/kris_boomer_sch.jpg
