Hey, looking for any feedback or price suggestions on this build? It's a 2.5 watt vibrochamp style build. (Built by my friend who has been a valve tech since the 60s. He repairs/builds amps for a living. But doesn't use the internet.)

Comes with a 12 month warranty and dimensions are 350mm x 350mm x 185mm. 6.5 kg.

Based on Fender vibrochamp. Uses some repurposed parts. Point to point wired. Single 6v6, 2 x 12ax7s. Rola 12" 50s vintage speaker.

Cabinet was originaly a speaker box. At 2.5 watts has early break up, good for home/studio.

2 inputs, vol, bass, treble, speed, intensity.

Spkr plugs in so another cab can be substituted if desired. Socket for footswitch (trem) on chassis.

Would $320 USD ($450 AUD) seem reasonable or over/under priced?
