OT: Show us your DIY tube amps

[alancohen]

Here is a very recent ( finished last week ) DIY triode amp, made by a long-time Altec 604 user from Saint Louis, Drummerwill :



The LP 845 amp: It took 4 months of planning..... - drummerwill - Tube DIY Asylum

But it has a buzz...that's not acceptable, is it?

Next I plan to improve the 10.0 volt output tube filament supply. Right now they are very quite, but a slight buzz on my 604's...


In my world, Mission 1 is rock solid reliability, mission 2 is dead quiet, both mechanically void of transformer buzz as well as electronically void of any speaker hum.

Without those features, it doesn't matter what the amp sounds like.
