Sony vs Tokin
Can anybody explain what the perceived sonic differences might be between the Sony and Tokin Sits. For those that have the Tokin and don't win the lottery. Thanks.

I like the idea of a switch on the front end cards. Can it be safely operated with the amplifier on?
You'll have to ask Nelson directly, as he's the only person who has heard both versions, and he's notoriously tight-lipped about describing subjective differences...
So just build the Token version and be happy, it's going to be awesome - as those who have built amps with that device are very pleased with it!
All these front-ends will drive it as well, and that's cool.

Wowzers the HMS Relentless reminds me of 1960's art and pop culture

A nice British naval theme on these front ends. I am old enough to remember Goldie on laugh in, body painting my missed calling.
Nice work Mark these should be lots of fun.

Yep, the dazzle paint job on the Relentless was characteristic of the inter-war period, and carried forward into early WWII.
The Scourge circuit reminds me of one of my favorite cards for the M2x. Wonder how that happened? 😉 The Bullwark front end reminds me of an early vacuum tube preamp. Inverted, of course. The PCB form factor looks like it has plenty of room for an old-timey tube circuit. A twin triode of some sort (6922 / E88CC) followed by high voltage bi-polars to drive the transformer.

Load the Bulwark gerbers into a free Gerber Viewer program of which there are several dozen online. Read the text on the Back Silk Screen layer. Its genealogy is written there for all to see. Depending on the featureset of your Viewer, you may want a mirror to help you read the text on the back of the board. Or do a screen-grab, load into Paint, and tell Paint to Flip Horizontal.
Me, I prefer www dot pcbxprt dot com because (a) it runs in your browser so there's no software install ; (b) they don't ask you to Register or to type your email address for their newsletter and advertisements.

Excellent idea.
The whole concept of tweeking the input stage by merely switching cards is perfect from a system matching perspective. That's a great tool for the hobbyist who try to voice his system to his taste.

Separate supply for MARAUDER?
Meant to type DREADNAUGHT /...
Seems like it would not be much more difficult than to simply have a separate supply for the stage and skip the booster?
What is the voltage the booster supplies?
Unless there is a reason this dilettante would not know (being a dilettante) you chose the booster for reasons other than the convenience of having only one raw supply? I presume the booster is also regulating the voltage - how critical is the quality of the regulation?
Plan on using this before the TOKIN after Ing. Pass shows us how to do it.
We are lucky you enjoy audio!

Wow, those FE boards look great! If I am lucky enough (fingers crossed) to get a VFET kit, I am definitely putting together and trying all the boards
Thanks for providing these designs Mark!

The First Watt M2x had it three years ago, here on this Forum and also in the diyAudio Store.
Let's consider the following three comments together, as a package:
What do these have in common? What thought pops into your head? Sometimes the general solution is easier to discover, than a solution for one specific case. Has the penny dropped?
Go to rot13.com and ask it to decode this character string:
TENAQQNHTUGRE OBNEQ --> QNHTUGRE OBNEQ --> ZBGURE OBNEQ
Surprising that nobody has independently thought of this yet.
Whoa, mind blown. That’s a great idea! I especially like the concept with the boosted voltage and phase inverter.

Would these work for a SIT-3 amp?
I've a FirstWatt SIT-3 amp with transformers on the input. I wonder if I can make use of these input cards and bypass the voltage step up transformer circuit in my SIT-3?

Thanks for these additional input cards Mark! Looking forward to both wining the lottery and finding a way to source these cards. At least for the PCBs, it would be ideal if they were made by the store and could be added to the kits parts.
Thanks again!
Rafa.

@RafaPolit, I don't work for the Store and I am not authorized to speak for the Store either . . . . . .
But I'm sure they are thinking VERY carefully about whether or not to sell these four additional Front End boards as bare PCBs, and I'm sure they are also thinking carefully about whether or not to create and sell parts kits for these four boards. I think if you sent a kind AND BRIEF email to the store, expressing your desire for boards or kits or both, they would be very glad to have your opinions and purchase preferences.
