Something I have always wondered....
Can I use two separate stereo amps to power one headphone?
Using a Darkvoice 336 as an example, because I am familiar with its bigger brother 337 having owned it for a couple years. The 337 I think is just two 336 circuits running dual mono in the same chassis. The 337 parallels each triode in each 6AS7G / 6080, for the R and L channels.
So could I take the R/L line outs from my source, split each into two equal signals with a parallel "Y" cable. So I'd have a Right-Y and a Left-Y to plug into a R-336 and a L-336. That gets amplified by each 336 dual triodes, and results in essentially two Right and two Left channels at the 1/4 stereo TRS jack.
A headphone + cable like the HD650/600 would have to be re-terminated with separate Right and Left 1/4 Stereo TRS plugs. Each plug tip & ring internally connected in parallel to sum the output of each 336 amp channels into each R/L headphone channels.
Would this work?
