Ok, Olaf - I think I've managed to implement all of the fixes to the schematics now per your last set of recommendations. Please check me on the vactrol and also on how I've applied the supply voltage to the PLEX MODE relay to power the LEDs. I don't think I need a resistor in front of the pin I applied the voltage to because the pins of that relay can handle 1A at 30VDC. I just put the appropriate resistors inline with the two LEDs. Here are the updated schematics:

LOOK DOWN A FEW POSTS FOR THE MAIN PREAMP SCHEMATIC. I UPDATED IT BECAUSE I FOUND A LOGIC PROBLEM. ALL EXPLAINED BELOW.

Oh... and here is an update to the layout replacing the purple LED with a blue one - I don't find any purple ones anywhere...

Thanks!

Oh, btw (total noob question, but...) - how do you mount the leds to the front panel? All I could find were 3mm and 5mm LEDS... they are really TINY! Is there a housing for them or what?

Oh yeah - now the fun part will be actually laying this all out on a board. Whew...

I'm gonna have to draw something up to scale...

Hi Steve,

will have a close look later today.
You don't need a 7 PIN - 5 PINs is enough b/c you just have "three" sets of relays, some of them are switched simult. - 2 sets for your soundmodes, one for the loop, one PIN for 6V and one for ground = 5.

Also (just a question of wiring) take the 6.3V AC for the rectification off the power tubes, not the preamp tubes (just leave the schem as it is).

Crap...

Ok, I realized the logic was wrong in my last schematic for me to implement the 5 pin footswitch. I have to make sure that PLEX_MODE_RELAY, ROD_MODE_RELAY AND MASTER_RELAY are all either off or on together. Then ZEN_MASTER_RELAY and LOOP_RELAY can function independently and I only need 3 pins of the 5 pin MIDI for switching. In my previous schematic, The PLEX_MODE_RELAY and ROD_MODE_RELAY work opposite of each other and that won't work. I had to change my manual DPDT switch in the schematic and also my PLEX__MODE_ RELAY connections to make this work. Can I do what I'm doing with that DPDT connecting both the ROD_MODE_RELAY and MASTER_RELAY to the same pin? I think so...

Check my logic here - Now if PLEX_MODE_RELAY, ROD_MODE_RELAY and MASTER_RELAY are off - we are in plex mode using the plex master. If they are all on, we are in rod mode using the rod master. Another interesting and unintended consequence is that I can use the Zen master in either plexi or rod mode. If I switch the ZEN_MASTER_RELAY on in either mode, the Zen master overrides either of the two regular masters. I really meant it only for rod mode, but I don't think it is a problem. Kinda like using a diode clipping boost in either mode. Correct?

Anyway here is the updated schematic:

How does the PPIMV come into play relative to the three masters on the front?

The PPIMV is available with all three masters up front to control overall volume. If you turn it all the way up, the one I use is completely out of the circuit. You can use the other masters to equalize between the modes and to get the amount of gain you want and then manage the overall volume through the PPIMV. My PeaceMaker was modded to have two masters pre and post PI and it worked really cool. You can also select "PLEX MODE" and crank the gain, plex master and PPIMV and you've effectively got a cranked Super Lead. You can do a lot of cool things for both recording and live playing with this amp.

You don't see the PPIMV because I haven't posted the power amp schematic which has the phase inverter, feedback circuit (presence control as well) and the rest of the power and output section.

Good Morning

relays: please use a R in front. You don't want each relay suck 1A from your PT, you know. You couldn't heat any tubes then The 1A refers to what it can switch, but not what the coil sucks . . . have a look at the coil data:
http://www.components.omron.com/compone ... A_0607.pdf
Normally its 30mA - so:
supply voltage - relay voltage/0.03 = R
assuming its 6.5 V supply and a 5V relay:
6.5V - 5V/0.03A = 50 Ohm

Yes, there's housings for 3 or 5mm LEDs available, black or chrome. What Peter (and I) do is simply a hole of 5mm (good driller needed), stick them into it and add a tiny drop of superglue.

Ok, so I need to put a 50 OHM resistor in front of the left coil input to each relay on the line from the 6V power supply? Is that correct? Also, since my power supply is 6V, shouldn't the resistor be 30 Ohm?

So everything else (all the logic, etc.) looks ok? The 6V I have going into the pin of PLEX_MODE_RELAY to power the LEDs is cool?

One other thing - so you and Peter just glue the housing in? Is this what it looks like:

Or is it like the wired plastic housings on this page:

Thanks, Olaf!

Steve,

Are you sure that the Jose Master is correct? BTW--I am on Metro as Guitar Adjuster. Reason I ask is I have some photo's of a Jose master off a Cameron modded 2204 that does not look like that at all.......

Allen - It is straight off the original hand drawn schematic of an original Jose Arredondo mod on page one of this thread with a very minor change for the switching.

Steve, you need to measure the supply voltage when its finished to have the exact value. Thats why the Rs can be a bit bigger in value now, Or - when you have measured it - just recalculate the Rs.

We just glue them in. Actuall with a fresh 5mm driller and a stand drill the 5mm LED fits tight into the hole, so that the glue isn't really needed. If you decide to use housings: metal of course.

 

[duesentrieb]

When you look at the two pics I've posted on page 1 (the footswitches), you can see that there are no housings and in the open enclosure (the grey), that the LEDs sits tight in its hole.

I've talked with Mark about this Master (after I've built that into an amp looong ago). So I guess its corrct, but a link to the pic(s) would be nice to verfy.
The way Steve has wired his up definitely works.

Ok, so the location of the Rs as I described where they go is correct, right?
