ABY switching - A different approach

[liagasg]

I've been studying the R.G Keen A/B/Y/ hum free splitter for a couple of days. I though of a different approach, and i would like your feedback.
Since the transformers circuit is used to drive the 2 outputs at the same time, i designed a splitter, using the transformers circuit ONLY in this state.
In the other state (the A or B function) the whole transformers circuit is bypassed, and the signal is driven directly to A or B output while keeping the other grounded (as well as the primary windings of the transformers)
The Input ground is directly connected to the outputs. The jacks are isolated from the box.
I didn't include the power section of the circuit.

I am just showing my idea as building blocks.
What do you think? Will it work or it already sucks?

I just noticed that the image doesn't load very fast.

Anybody any comment on this design?

Gives me a Security Certificate Error. Doesn't want to load.

Put it in Single A:



The input (guitar) drives the A output *AND* the transformer secondary. We had the opamps because a guitar won't drive a transformer well (and a low-cost tranny very poorly), so this misses the point.

Worse, your switching puts a short on the other transformer winding. If the tranny were perfect, this would be a dead-short on the other winding. Since it's a low-cost tranny, it's a poor short, but sure to really clobber your guitar signal.

I suspect R.G. studied the problem for more than a few days, and felt the plan he gave was a reasonable balance between transparency and excess switching complexity.

Have already thought of that. As a matter of fact, what I've posted is my 2nd thought.

Here is the First one. It uses separate outputs, selected by the switch

Nobody? Nothing?
