Not sure what you're asking. Do you already have a Valve Jr. that you want to convert? If so, what version? Or are you talking about building a head from scratch?Quote:

I'd like to get a Vox voiced one to replace my dead EVJ's board.
I'm talking about building one from scratch. It might be more cost effective to buy a head and replace it with a complete board.
About halfway down this page:Quote:

I expect that it would be considerably cheaper to buy a VJr head and modify it than to build from scratch. The cost of transformers, chassis, hardware and cabinet would add up pretty fast. I'd suggest looking for a used head on eBay or CL.Quote:

I would buy a used amp to further increase your savings.Quote:

I'm really liking what I see so far.
So, it looks like you had to cut off the stock connectors and solder the wires directly to the board, right? Do they supply adequate instructions on wire placement? It sounds like yo and Tung had to adapt your past mod's to the new board. My only mod is a tone pot.
Also, how does the EVJ sound now after you've had a chance to play with it?
Yes, had to cut off the stock spade connectors on the transformer wiring and solder directly to the board. The layout diagram makes it pretty clear what you have to do, I thought. There are some grounding wires that have to be added, too, also shown on the layout.Quote:

Mallory 150 or Orange Drop cap's, as well as 1 watt carbon film or 1/2 watt carbon comp resisters. I'm not sure if they make much of a difference in tone or reliability.
The carbon films are the better technology on the resistors--less noisy. Carbon comp rezzies get talked up on the basis of "vintage mojo", whatever the hell that is. Snake oil, IMO. Less noise = mo' better, in my book.Quote:

My EVJ board arrived today. Its the Voxy version as well. Hopefully I'll wire it up next week.

Ah the yellow board. Should provide slightly glassier treble and more intricately shaped highs than the red one DVM has.... :poke
You know it!Quote:

Wait, that's' a Vox/Fender version..it has an Orange Drop AND a Mallory! Are you sure it won't explode or something? What if the Orange Drop goes for Declaration of Independence?
But the red boards have more tonal warmth and superior gain characteristics. This is widely known.... :frenchQuote:

BTW, Bloozcat just got one of these new VJr boards, too....
Yep, mine came in last Thursday, one day before I went out of town for 4-days. I should get started on it this week the good Lord willin' and the creek don't rise.
And of course, mine is a red board as well.... :socool
Yes, but the yellow board will make women within range turn to puddy in your hands. It's a known fact! :luvitQuote:
