I just create my drawings in Illustrator and export as EPS, and they do the rest. You can see at least five examples of their work on my amps for sale: https://reverb.com/shop/superconductormusic
Thanks xtian! I will ping them during the weekend.
Cheers!

Just received my faceplates.
Great job by Terry at IndCom Graphics.
Items arrived spotless in 2 weeks and very decent pricing. I must say the aluminum set looks better than the picture.

Next is drilling holes in the chassis!

Nice! But I can’t tell a think from the photo. Can you post a macro shot of the aluminum one, especially the text?
I build and repair tube amps. http://amps.monkeymatic.com

Xtian, hard to get a good shot at the texture. Here it is. I should have added these are in acrylic not metal.

Got some time this weekend to drill the holes in the chassis. So far, front and back are done. Next I will have to unmount the OTs from the donor amp, draw a blank and position it on the chassis to get it right. I also need to drill all the small holes on the bottom side.

Cheers !ImageImage

Hello folks,

A little update on the build :
- trannies transfered from the donor amp
- heaters soldered (hopefully right)

I realized the main power switch is really close to the second power tube socket.
No contact but it is close... too close ?
I though about reversing the switch upside down.

Any thoughts ampgarage experts?

I have not decided yet if it will be black or silver.. I have a preference for silver though..

Cheers.

Fred.

Maybe you can "shrink wrap the mains" (not sure how to say it in english) & slightly bend some connectors?

I prefer the black control plate - also. I find it looks more refined, which suits such an amp :wink:

You mean using some shrink tube on the main switch connectors? That could be an option. No risk of melting and fire?

No risk of mething and fire?

I was tempted to joke about wrapping after solder, rather than before :mrgreen:

Dunno why would that happen? I've already seen this on amp gutshots. This is not something I'd worry about -

Good to know! I am learning a lot here and I must say that my electricity’s knowledge is quite limited. So safety is my main concern.

Heatshrinking electric components as an insulator is very common practice and safe. It can't avoid every possible problem, but it reduces chances of arcing and accidental contact etc.

Phil, thanks for the feedback ! I will officially heat shrink !

Marcus, thanks for the kind words. Hopefully it may work out fine.

HRM needs some Lovin'

Post by fred.violleau »

A few questions here:

Is my AC powering correct?

I have AC ground connected with the ground star on the chassis. This ground star also receives the center taps of my Power transformer.

I think that my light bulb can accept 120 v which is why I connected it to the main switch. Is there a way to test the light bulb before having to power up?

Also, I have seen different ways to deal with the neutral AC : sometimes It is connected directly to the power transformer (ceriatone layout), sometimes it is connected to the fuse which is what I did). Which way is best?

Finally, my PT shoots 6.3v at 6A. These were connected to the tube heaters. Is it too much? It is almost twice what I saw on the ceriatone layout...

Thanks for the help!
