Wow, it actually works!

At lunch break today I finally dared to switch on my home made valve (tube) guitar amplifier and to my work mates surprise and my relief no bang, smoke or sizzling noises! So I connected it temporarily to the PC's sound and it came out loud and clear with NO hum! Can't wait to plug a guitar into it! Tomorrow I have to take multiple voltage measurements and do some maths to work out how hard the new tubes are working -too lower wattage and they won't sound their best-too much and they won't last as long. Then I can see if I can get the final (or first) tube working, it's just an option and can be switched in and out but I'm still a couple of components short. I've learnt so much already by building this thing!
