High sensitivity and controlled directivity sonic hallmarks... You got the prototype loudspeaker from Troels or you made your own copy already?

i was a bit skeptical with the PA driver,,,but i must say,,they surprised me

Beardman, thank you very much! Troels' speakers are well known for excellent dispersion and it's really interesting to apply that on vintage legendary designs.

Here is the one I will be providing with optional kits for BC327-40 in the next GB.
Of course anyone who has existing boards can purchased 4 of these with matched quad of BC327-40.
Mouser part : 535-03-0518-10
03-0518-10 Aries Electronics | Mouser

I am not a fan of cutting those pieces into smaller units.

A good quality i.c socket is a source for transistor sockets.

Not to forget mentioning, the DCG3 boards from now on will be marked V1.03. I found the time to do little things, and I asked CRT to retouch on it, like I thought of a way to have the relay's resting position at GND and not at NC (no connection) but not to be shorting the output either, broke the ground lane in two channels and put bridge pads underneath so your grounding scheme in builds can be fully flexible, there is J3 printed for the BF256 on the board too as in the schematic now, not Q5. Performance wise nothing changes, just little perfectionist touches on the board's practicality.

But clip those transistor legs shorter for less inductance and better mechanical rigidity
