diy tube preamp with buffer stage any recognize this circuit or can tell me there opinions on setup

[toe1111]

hey guys i was hoping anybody may recognize this circuit,
it was pulled from a diy amp and it was the front stage, driving what looked like a class hood 1969 stereo circuit ,

the first pair of tubes to the left are 12ax7 i rewired to take the Russian ones and i think going by the heater pin locations the gain stage on right are the same but possibly could be 6cg7 im not sure yet,

imput is on left the two white mundorf caps, and outputs on the right with the resistors and ceramic cap,

its running at about 230v off a voltage doubler
i just want to power it up throw a volume knob on and see how it sounds but absolute bonus it came with vintage mullard 12ax7 long plates score

Can't tell what the circuit/schematic/build is without a view of the interconnections on the underside of the veroboard and pin voltages on the valves.
Obviously a home made effort. Probably best to start again with a known good design.
