I have drawn up schematics for Mazerati-GT, Stangray ,and Mini Z , so i decided to make a zip-file of all the known Z layouts and schematics.

this tone control is great but you must know it's a mid scooper and not a low loss one.briggs wrote:I really like the look of the Carmen Ghai's tone control setup. I think I might give it a try
personnaly i like to insert a 47KA pot/trim between the 10nf and ground that let me dial the amount of mid-scoop/gain-drop. of course with this pot/trim maxed the tone control is less effective but restored mids sound better for distortion IMHO.
last thing, if it work backward your wiring is correct

I think its a 4k ultra linear.fluzo wrote:Thank you.
Does anybody know the Route 66 transformer specs? OT primary impedance in particular.
Thanks. Why ultralinear? On the schematic it looks like normal push-pull operation...

no screen choke or resistor supply, KT66 screens are connected to a tap at the output transformer (43%). so it is ultralinear. the MOV/genalex datasheet is showing a 8K OT (with higher voltage) . i don't know what the good Dr use in it, but 6K6 and 8K OT seem common with KT66.

I havent seen a Route 66 schematic yet, but I keep thinking its gotta be an old mullard circuit.
You look in the mullard amp circuit book, theres a Ef86, and 2 kt66 amp that just seems to scream the route 66 to me...
I could just be really goofy too.

Hi, I am trying to build mini z for my first tube amp project.
I have a few questions.
1. It was impossible for me to get 40uF 450V and 20uF 450V capacitors used in Rectifier (Bridge?) section.
I was able to get 47uF 450V and 22uF 450V.
Values didn't really make a huge difference in PSU Designer graph but I would like to make sure if I can use those.
2. What should I use for Rectifier Diodes, 1N4001?
3. What would be the fuse size? is 1A sufficient?
I would really appreciate your help.

They will be fine. Caps are usually 20% unless marked differently, so a few uF won't make that much difference, if any.shicky wrote:Hi, I am trying to build mini z for my first tube amp project.

I'd use 1N4007s, rated for 1A, 1000V.shicky wrote: 2. What should I use for Rectifier Diodes, 1N4001?

Not sure, I usually use 2A fuses in builds of this power level.
