Hi all,

I would like to invite you to share your experience with High Power Single Ended Amplifier (greater than 20W output).

No experiences yet, but Iīm working on a pair of 813 monoblocks that should reach 26-27W each. 900V B+, 9,2k plate load and grid pushed to +20V at peaks.

Hi Fuling,

What kind of transformer do you plan to use in your amp?

Hi

Lundahl ITīs and OPTīs, DIY:ed power transformers, Hammond chokes.

Iīve ordered a pair of LL1688 OPTīs, itīs a new model intended for 845 amps. I ordered mine with a slightly bigger airgap to allow 80mA instead of the original 70.

ITīs are LL1671/50mA driven by 6C19īs
