[Chris-in-LA]

Right, but you could have this OT sooner if you don’t want to wait on Mojotone to deliver.

 

[Rotorcraft230]

They are in stock, but I’m ok, thanks for looking for that. Don’t mind waiting.

I get going on these builds and get behind on honey-do stuff, it’s a good break.

Love that big ol' honkin' iron.

I'm still planning out my 2204 in DIY. Starting point is the chassis, board, etc. from Valvestorm/Metro, w/ Heyboer iron.

Are you staying close to stock values on everything, cold clipper, etc.?

Staying stock for now, we’ll see how it sounds then. All the transformers are Heyboer,they are big and heavy, just the way I like it.

If your build was a pair of legs, it would look like this!
Congrats! on making a great gift for your son.

[Rotorcraft230]

Installed the turret board and started the wiring

So far, what is yours and your sons favorite amp?

As far as the kits go, gotta be Ceriatone All Access Plexi51. He well and I really like the Plexi51 sound. Aw also like the Ceriatone Dumble as well.

Very interesting. Have you ever modded any of them? I'll be curious to see what you all think about how this one compares to the others.

I typically don’t mod them, we seem to be happy with the results.

Here is some more progress
HT from switch to board, bias pot and wires, HT to filter.

 

[Rotorcraft230]

Control pots wiring done.

 

[Rotorcraft230]

Finished the power tube sockets and now in to the PI.

What a beauty

I just realized that Mojotone upped their game on the 2204 kits and are supplying multi-colored wire. Mine came with mostly white wire, three or four years ago.
