Nice project!

I built a valve (tube) amp kit many years ago (push pull stereo with EL34 outputs). This was going strong for many years, but last week, suddenly developed a pronounced hum in the speakers which I took to be failing electrolytics. New caps are on order. The originals lasted ~ 20 years and many hours, despite being a brand of which I had never heard (Trobo). The replacements will be Nichicon 105°C types.

Looking forward to the outcome of your project.

I don't hold with furniture that talks.
