2011年11月13日 · Bgw amp Pcb Hello again; I took the time to open one of my Bgw amps to check the Pcb numbering. Mine are model 750G and have the same pcb number T9007-0760.

2016年4月12日 · Hi Duke I didn't know it was a copy of the BGW. No wonder the layout looks the same. Two heatsinks on top with fins facing up. I had a BGW 750G in my humble recording studio during the 80s. Beautiful piece of engineering. And I love those LEDs in the display panel.
