Yes. It says 'total resistance is 250' which means the 261 and 6040 are connected in parallel.
Even without that note, the way it is drawn should make that clear.
BTW This is a fine example of how NOT to draw a schematic. Very amateurish. Is this an existing design?

Why would there be 3 fets on the negative voltage rail and 2 on the positive? I posted earlier then deleted my post to check Idss on J112 and J175. J175 should have higher Idss. Also why 0.5 V difference after the fets? Any ideas?
Yes, probably to construct two complementary matched 'devices'. Note that this is all open loop so you must go to heroic measures to get some acceptable linearity from it.
BTW in its original complete form the schematic drawing does make sense so I withdraw my earlier 'amateurish' comment...

Is this the Blowtorch?? Bligh me! I thought it was a well guarded secret? Now anybody and his mom can build one! Not that I would, but in theory. 😎
Would be quite a feat for us pitchfork wielding villagers!

was it a secret-- !?
atomic bomb on the Internet can be found))))
I do not like secrets! Good Kondo companies! Audionote do not make secrets from their schemes - try again!
I'm probably the first idiot who makes a copy it's all about good old transistors that are no longer available
The last question!?)))
- Is this circuit suitable for a 47K head load MM ?

Close enough 😀. But closer to the Vendetta SCP-2, though.
The CTC Blowtorch is balanced: Uskok preamplifier

Does this circuit work with 47k load?
separately include 47 k? for MM
Mc-separately (green)
Or MC or MM.
47k-- remove when MC

The impedance seen by the input will have no effect on the circuit operation. The gain of the circuit is the same for both conditions.
