Nice place. Hope you enjoy your stay. Another week to go for my winter break after the school holidays. Will try to get some work done on the amp.

I bought a can of black spray paint and gave a few quick coats yesterday. Unfortunately a few runs, note to self: please practice in future on non-critical sheet of metal. After 12 hours overnight seems mostly dry but will leave for a few days before attaching things.

Also cleaned the pcb board with isopropyl alcohol after reading about recommended cleaning solvents. Hasn't worked well as it has left a smudgy mess. Must be something better- are there any suggestions from the community? I'll post a few picks soon.

I've looked at a few of these kits because I currently have an abundance of 6SN7s and simular and would like to make a preamp with them.

I see you can buy bare boards which would be the way to go for me. Then pick your parts. But I can build a single stage preamp on two 50cent 5 tag tag strips so I think why pay for a PCB when a buck will do the same job.

Ideally I'd like to be able to do something like that too. Pcb projects are probably a little easier for a noob like me to get started. And I now recognise some of the disadvantages of pcb amps. If this project turns out I would like to have a go at the 6sn7 preamp you and Matt from memory collaborated on. I may need it if it turns out I extra gain is needed for this pcb amp as reported elsewhere.

Much better than a bare chassis.
