nope

put shortie instead of R104,R204
or nice looking 0R resistors

Thanks for clarifying Zen Mod! R104/204 was actually my first choice but I second guessed myself. Still learning how to interpret and follow the wiring diagrams and component connections. Iíll read through Nelsonís circuit description again. One day Iíll get to all of Papaís papers to get a better understanding of his circuits 😊

Does the same apply when adding iron to versions of the Salas DCB1 regarding pulling the series resistor on the output?

I have a black Hypnotize version which to my understanding was just an aesthetic pcb color choice by Tea Bag when he had these boards made. The circuit and layout shown appear to be identical to my board.

Iíve circled what I think is the series output resistors that would have to be removed in each image...which of course are some of the fancy Texas Componets foils I splurged on.

Iíd just like confirmation Iíve got things right before I might try this.

Thanks Zen...thought of another question

I have my DCB1 wired with two pair of output RCAs so that I can send the signal to a powered sub and my ACAs driving full range drivers in horns currently.

There is a 100 Ohm resistor in series with the positive signal wiring between the first and second pair of outputs. It was advised to add the resistor between the outputs in the DCB1 build thread. I think this was related to maintaining proper buffer operation?

I want to keep the dual outputs.

I have a B5 I would like to implement in my next stage of this systemís evolution.

The sub may still be desired.

One set of outputs would go to the sub and the other would connect to the B5. The B5 in turn would be driving separate amplifiers for the high and low frequencies.

Is there anything I need to worry about as far driving the additional equipment or how I am initially dividing the signal in the DCB1 when installing the iron just before the dual output RCAs?

I will be going into the DCB1 to try some different pots and rework the signal wiring with some shielded cable as well as trying to improve the grounding layout. So now is the time to sort it all out.

Pic below of the outputs for reference.

Thanks again in advance.

at output side of gadget you can keep those 100R as sort of separating parts between two outputs

even if I would use lower value - 22 or 33R , or not at all

in my Iron Pumpkins I'm using just wires between paralleled outputs , no biggie

I'd appreciate a list of transformer options for iron pre, european ones more so.

Also, what would be the tech specs for a custom made standard EI. Such as core size, wire size, number of turns or impedance / dc resistance.

There,s a guy here who can make them. Being a guitar freak too I could even vacuum wax pot them though that what probaly be unnecessary.

Also there seems to be a number of 1200:1200 transformers on offer. Some center tapped on primary and secondary coil. Could those be used? Those could give +6db with galvanic isolation too?

Mr. Zen, iskra tl-1m 600:600 comming in... for 1:2 connect all colis in series, connect everything to amp in both ends and tap the buffer + in the middle?

yup

excellent xformers

take care of windings phase ... observe red dots on edited pic

edit:

1 to GND
2+3 short
4+5 short , that's IN (from buffer)
6+7 short
8 OUT

that way you'll have 6db gain
