Default 5 Ch Patek

Very Nice Peter!!!

Where do the power supplies plug in?....those small black circles on the back panel? And have you made matching cases for them?

Are the sinks in the middle solid copper? The color almost looks like anodized aluminum.

You appear to have a complete 2 ch board for each channel.....what is the configuration? I think you mentioned once that you could only run them bridged with balanced outputs?

Are you planning to sell a 5-ch version?

Robert

The black rubber grommets are for PS cables (permanent installation on the amp).

There will be two cases for PS, but not matching, I wouldn't reach the price point then.

All 3 bars are solid copper, same for the front sub-plate. They look dark because I treated them with patina for more uniform appearance.

Each board is one channel (this is LM3875 chip).

That amp was actually a custom order, I'm not sure if I offer 5 channel version as a product.

All aluminum is hand brushed and treated with alodine. All machining done on a table saw.

Perforated top panel allows good ventilation. Copper plate inserts provide not only more sophisticated looks but also create air channels for side panel cooling.

Here's the close up of the inside. As with all Pateks, the brass cones are located directly over the chips.

Copper wire creates star ground for 2 channels.

Cool. Looks like room on the inside for up to 3 more channels... might be a bit of a trick to find room on the back for speakers posts thou.

well if it ever does happen to you look up the rm 10k mute resister that was the problem


these chips are made to last. it was a big static spark.
