"3 channels Dual/Triple Rectifier Mesa Boogie Cover with Footswitch"





Viele Auskunfte so wie möglich,  zu Frankreich

Jetzt habe ich schon so nen riesen Monitor, doch dein Bild ist zu groß.

Hallo efirre 
 
 
Trotz deinem gewaltigem Bild, würde es mich interessieren, mit welchem Programm du dies erzeugt hast

Bin ich alkoholisiert, oder warum sind da 8 Endröhren drauf?   
Ich dachte der Tripple hat 6 Endröhren?

Preamp: 5x 12AX7
amp    : 4x 6L6 and 4xEL34 (with commutation select)
output transformer: Hammond 1650W
power transformer: Hand made for really have 150W

Progressive start, µprocessor and reed relays for commutation, and protection, mesa footswitch compatible, midi commutation ...

I'll made a website for the a to z realisation

(Nota: pictures was made with mechanical desktop 2005)

Thanks for your interrest...

Moin,

Hallo efirre

Ich vermute er hats mit Autodeskinventor oder Solidworks gezeichnet oder ein anderes Änlcihes CAD Programm. MAche sowas öfters in der Schule wenn ich lange weile hab .

@Eugen

Danke für dein Tip! Habe es so in dieser Richtung vermutet. Tja, wenn ich so an meine Konstrukteurenzeit zurückdenke, da hatten wir alle noch ein "Brett vorm Kopf" im warsten Sinne des Wortes . Mit CAD hatte ich dann nur nur kurz Bekanntschaft (Medusa).

Aber ist denn die Schule so langweilig, oder bist du einfach schon zu gut dazu  wenn du dich so langweilst?

Hey efirre,

Your project sounds interesting, a little similar to mine 

* uProcessor + relay controlled
* Progressive startup
* Tube failsafe monitoring
* Speaker jack failsafe (poweramp remains on standby until speaker jack is connected)
* uProcessor controlled bias measuring & adjustment
* Midi
* 2x Cooling fans inside

* 3 Assignable channels
* 8 Assignable preamps:
  - Lonestar Cleans
  - Mark IV Lead
  - Mark IV R1
  - Recto Ch2 Vintage
  - Recto Ch2 Modern
  - Recto Ch3 Vintage
  - Recto Ch3 Modern
  - ENGL
* Full channel cloning - so ANY combination of preamps is possible
* 7 Button footswitch: Ch1 - Ch2 - Ch3 - Boost - LOOP - EQ - Reverb
* Knob "pulls" on all 3 channels (similair to markIV pulls)
  - Gain: bright | Volume: bright | Bass: fat | Master: silent recording
* 5 band eq
* Channel selection button on front panel

* Rear: Each channel has it's own controls:
  - Loop select: Serial / Parallel
  - Loop on / off / auto
  - Loop: send level
  - Loop: return level
  - Simulclass / Class A
  - Pentode / Triode switch
  - Reverb: level
  - Reverb: on / off / auto
  - EQ: on / off / auto
  - Boost: level
  - Boost: on / off / auto

It's going to be crazy having a Recto preamp mated to a Simulclass poweramp, with Mark-style pulls!!! Or ENGL with Simul power!

The major problem for me right now is switching between the preamps without noise - switching components in the preamp cathode is o.k., but switching anode resistors

I can't wait for this baby it'll be a few hard months of work!

Take it easy,

Jonny

Here's the front panel layout (it's a short head design, inside the pcbs will have to be stacked!!)

I need to update it a little bit, but it gives a good idea (the reverb will probably go at the back, and the preamp selector now has 8 modes, don't know what switch to use ):

What do you guys think?

[Hostettler]

@BesaMoogie

Looks not bad! How about the schematic? Show it us now!

Hey Hoschi!

I have yet to finish the schematic, as you can imagine it's hard work! I need much help & guidance from this forum to get there, basically, I'm building my dream amp.

You are from Lyss? I used to live in Willer-bei-Seedorf as a child!!! It's a small world!

mfg,

Jonny

[Hostettler]

@Jonny

No really? Is hardly to be believed!
Yes I live in Lyss and when did you in Wiler live?
Sorry, about my English, but it is no more so good...

Greetings from Lyss close at Wiler/Seedorf

@ hostettler

Yes, I lived in Willer between 1990 and 1992, when I was 12 years old!

Anyway, this amp is proving to be quite alot of hard work!! But it'll be worth it.

I've decided that I'm going to use the replacement MarkIV output transformer and power transformer. And I don't trust the Mark IV-A schematics, so I'm going to hire out a MkIV-B and blueprint it.

mfg,

Jonny
