Macthed Tubes in BeePre2 and 2x Kaiju 300B

[Eddie TT]

To be pedantic, the Kaiju as monobloc effectively places the two tubes in series, not in parallel. This has some technical advantages, though I don't know how audible that may be. We use the term "bridged" to distinguish it from "parallel."

This Question came up for me after reading the above quote from Paul J.

If you had a BeePre and 2 Kaiju mono blocks,
Does the signal go from BeePre to stage one then stage two of the Kaiju?

Would you need two have a matched Pair of 300Bs for the BeePre and a matched quad for the 2 Kaiju's.

Or could you use 3 matched pairs moving them to suit your taste from BeePre to Kaiju in any order?

The bridged monobloc Kaiju feeds the single input to both tubes, whose outputs are then wired in series so the voltages add. Both channels get the same signal at the same time from the same source. The main reason is that the tubes do not interfere with each other even if they are not matched. (Well, OK, there is a bit of effect, but it's ten times less than with paralleled tubes.) None of our amps have a critical need for matching.

This applies to Stereomour, S.E.X., and Seductor as well.
