Still my favorite photo of this audio badass! 1963 LP in his Oakland NJ studio.

Interesting little combo amp. 1989 Yamaha T100C. Designed by Soldano. Basically a SLO-100 in a combo with cheaper parts. Some poorly done fixes/mods with a few tiny explosions here and there. This amp will be a little monster when I'm finished.

Clone of a Crowther Hot Cake. This pedal from New Zealand gets smooth distortion from over-driving an Integrated Circuit instead of a diode(or magic diodes like the Klon). I got the idea after looking at left over routing boards from an old Neve channel strip. Filled with high end audio IC's they don't make anymore. The same chip is used in the Hot Cake and one other pedal I will build next.

Mic/Line pre-amp with EQ harvested from a Neve 8108 console. Mounted in a Labok chassis. PITA to work on but sound killer running just about anything through them. They do smell like 1981 :) https://www.historyofrecording.com/neve8108.html

Speakers do not like heat. When you drive them too hard this can happen to a $300+ driver! Remember the controls on a typical power amplifier are not volume controls!

From Rane note 135: Much confusion surrounds power amplifier controls. First, let's establish that power amplifier "level/volume/gain" controls are input sensitivity controls. (no matter how they are calibrated.) They are not power controls. They have absolutely nothing to do with output power. They are sensitivity controls, i.e., these controls determine exactly what input level will cause the amplifier to produce full power. Or, if you prefer, they determine just how sensitive the amplifier is. For example, they might be set such that an input level of +4 dBu causes full power, or such that an input level of +20 dBu causes full power, or whatever-input-level-your-system-may-require, causes full power.

Amplifier input sensitivity controls do not change the available output power. They only change the input level required to produce full output power. Clearly understanding the above, makes setting these controls elementary. You want the maximum system signal to cause full power at the amplifier.

Klon clone with the unobtanium diodes from the '80's I found at a yard sale! We will see if there is mojo or not.
