RE: My 2 cents

Posted by sganti on October 29, 2021 at 20:29:17:

I built a 805 amp with monolith magnetic 3.5K output transformers with 16 Ohms local feedback, and it sounded great. Biased at +28V, it was driven by a mosfet source follower.

I went overboard using 211 as a driver :-). Its 2 chassis per monoblock. The power supply is a separate chassis. The parts selection was carefully chosen
- Coleman +ve Bias Supply
- Bartola Valves -- Ale's source follower modules
- Daitron low noise SMPS supplies
- amphenol 97 series connectors

I had the amp for 2 years before building a 211 driving 211 with monolith magnetics 15K output transformers, parts from the folks as above.

Repurposed the 805 to 211 driving 845 with MQ FS100 10K transformers I had on hand a friend.

Now I am planning a simpler 805 build, single chassis monoblocks with 5687 as the driver with EX001 plate choke as the plate load. Will reuse the same 3.5K output transformers.

I was just responding on 805 sound. Made well, they sound punchy, powerful and can handle any music thrown at them
thx
