FS: 4 Channel Parallel LM4780 gainclone
The pcbs are BrianGT LM4780. Inside is a 800VA 31 secondary toroid, Rail voltages of approx 43V. No problems with thermal shutdown. 54,000uF per rail. I'll probably part this out if it doesn't sell whole. I will post pictures when I get home today. All questions welcome!
Asking around $300, I'm willing to negotiate the price though. |

I checked the heatsink temp with a meat thermometer. I don't know where the non-contact thermometer ran off to...At the die, it is 113F and on the fins it is 94F. It doesn't heat up beyond this much when puttin' out the power. I do have 8 inputs there, I thought about going to a 8 channel output, so I wanted to have the option. Use the top four unbalanced inputs. I realize that the toroid has no magnetic shielding, but I hear no buzz/hum, so I didn't bother with making a cup for it. -Matt |
