Neumann U67 Clone : D-U67 Tube Microphone Build Thread.

[Khron]

edit: would this one fit? https://www.mouser.ch/ProductDetail/Switchcraft/QG7M?qs=sGAEpiMZZMvlX3nhDDO4AG9O2r1U3qeLy2Dp6uyqBPg=

If you really wanna pay that much just for that, sure, that'll fit, but...

But in case you'd like to pay 10 times less (and still be left over with a shell, that the 3-pin XLR insert your mic body may or may not have come with will fit)...

Plus decent enough prices on other parts you might need(?)...

I've been using these with no issue:

https://www.aliexpress.us/item/3256...st_main.5.7b241802yKK3pY&gatewayAdapt=glo2usa

Spend more on the shipping than on the parts, but still cheaper than other options.

The UPS (express) Saver can even get a package at least to Finland the next business day after ordering (if one places the order by noon or so)

Delivery time of 2-4 weeks, or..?

The last ones I ordered were on 27/7/24 and they were delivered 2/8/24, ~ 1 week.

I just ordered a couple more so we'll see if they're still on top of it.

I am in southern California so it's mostly just a trip across the Pacific so that might help. Other destinations may be more challenging.

do you guys know any alternatives to order the pad, lc and pattern switches. i ordered them from Dan but canada post is still on strike and it's literally the only thing missing from my build

EDIT: these perhaps?

Putting my xmas Mouser order in and see there are 400Meg resistors in the BOM. Not in stock...any alternative value ok?

470meg is fine. 390meg would be even closer, but a slightly more oddball value.

Thanking you once again Khron. 470 is in stock

so i started assembling the PSU(230V) and am not 100% sure about the wiring/the measurements.

I get a correct voltage at b+ but only -0.4 V at H- ..... i have the FS20-300 Triad Transformer. I bridged 2 and three on the primary. do i have to bridge 6 and 7 on the secondary as well?

I'm thankful for every suggestion


Edit: So i bridged the secondary and now get 220V at B+ and at H- (-17.10) is that ok to proceed or do i need to get H- to -16VDC ?

 

[happyforreal]

So about mounting the moby bv12.... i have the regular pcb set and thought it would be nice to mount it to the ami t67 pcb. anyone else tried this, and are there any downsides/problems to expect this way? do i need to put an insulation between the transformer and the pcb?

 

[doqmemory]

anyone else tried this

Yes, works fine. No insulation needed. I wired directly to the main board, so the small PCB is just for mounting the transformer to the body.
