Solid-state power amp in

[Miyagi_83]

Hello, everyone.
I've got this old solid-state 2x12 guitar combo from East Germany called Vermona Regent 1040. Generally, the amp is operational. It does need some care and attention, like a cap job among others, but it works. I'm not too big on the preamp, though, so I figured I'd leave the output section intact and work on the A NEW preamp.
So, my idea was to first build some kind of input buffer with voltage limiting. Having researched the net, I figured I'd try something like in the attached image. So, if anyone more skilled than me could take a look and tell me whether there are any design flaws there, I'd greatly appreciate that.

Thanks in advance,
M.

wire up a bread board, slap an AC sig in, scope the out, let us know

Hi, shooter.

scope the out

No can do. Ain't got no scope :( But that'll change. Pretty soon.
The only thing I'd like to know at the moment is whether the schematic posted is missing anything or not. I'm comfortable with tubes but I still need guidance on solid-state, so I might be asking a rookie question here.
Thanks for taking the time to reply.
