I bought a pair of V3 G.TENs and received them yesterday. I just built the first unit and everything went great so far.
But I noticed something weird, when moving on to the DOA (I got the 2520 style DOA that was offered with the kits).
The parts and their descriptions on the bags don't make any sense at all for the supplied PCBs. Starting with the diodes, the bag says there are 1N4148 -> D1 (2x), D2, D3.
But the PCB has designations for D1-D8 (and there are no other diodes).
I checked the transistors as well and they seem to be weird, too.
Is there anything I'm missing? Or any build document to clear this up?
Thanks and cheers,
Ha, my fault. That's Quad Eight AM10 pcb. Don't know how it ended up in the box with 2520bc boards and as a result you have. As I sad before - will send you 2520 kit for free, sorry about that. Please send me PM with your address.Are you sure that's the right PCB for the kit? I don't see the reason for two different ones.
Hi Bobby,Finished one of my Ver.2 kits. Thank you for providing this eq project. One question. Is the transformer wiring of Ver.2 different than Ver.1? In Ver.1 manual there were guidelines to ground unused winding (ORG or YEL wires) and connect it to 0V, for example to RED pad, But in Ver.2 Manual no such guidelines. I assume I can just hook the Typical 2503 pinout color code to their respected pins wiring for ver.2 boards. As is, I have it wired like ver.1 and it seems to be 1:2 ratio unity gain.
I think you can leave it.Would you recommend that I change the trx wiring on my ver.1 board to reflect this parallel primary wiring for the excess winding, or leave the orange wire grounded to 0v?
