My last PA

Fob · 24th June 2011, 11:42 AM

I don’t have posts over the last two years, so I decide to shine with one. I got some help from you people, in the past for specific power supply, thanks. I’m not audio fan but I play casually with microphones for surveillance and with industrial communications and control. So these days I needed an AC power current source with 6A RMS capability and I build one. It was power Howland amplifier and power voltage follower in bridge all of them in ClassB. It was for current transformers tuning. The sine wave generator was “bubba” with for RCs.
In the midpoint of work I made power operational amplifier. I don’t have a seller for APEX power products around me so I made two discrete of them. I want to share it.
English is not my native lang., so I’m sorry (not very) for the grammar.
