The internals: showing the ESP modules and the transformer. I used a P05 power supply powered by a DSE 15VA transformer, P09 24db linkwitz riley crossover board and P88 preamp. The preamp has a LM4562 opamp on the input and a OPA2134 on the output. All the opamps in the crossover and balanced output transmitters are NE5532
