[sdiy] transformers, power amps, and op amps.

"Line level" varies a bit, but you can expect +/-0.5V to +/-2V signal levels. You can boost this to "modular synth" levels (often +/-5V, e.g. 10Vpp in a Eurorack modular with +/-12V supply, like your amp uses) using an op-amp. There's no need for transformers.
