av98m 0 Report post Posted September 3, 2004 Another look at the predecessor to Firefox's current revision of the Big Ben Headphone Amp. I really just wanted to play around with black and white pics. Signal section. That's a pretty big heatsink for the 4 opa627bp opamps. Yeah, I know, everything's hidden by the heatsink and the board. Protection against reverse engineering? Close-up of the coupling caps(Hovland Musicaps). Look carefully under the board you can see a film cap peeking out. There are 4 of them under the board. 1 for bypassing each opamp. Close-up of the 2 Neutrik combi-jacks. 5N (99.999%) teflon insulated silver wire is used for the entire signal section. The power supply section. Transformer is a Talema encapsulated model. Close-up of the power supply caps. DT880s plugged into the twin Neutrik combi-jacks. You can also drive 2 headphones with normal 1/4inch plugs. One final look at the signal and psu sections side by side. Both are separately cased and connected via XLR jacks on the back. Share this post Link to post Share on other sites
