Thanks. Just found this thread and will try to order one directly from the Italian hifi2000 store.

I don't think they sell the back panel kit. I'm fairly certain you have to order through the diyaudio store.

Right you are
Hello Peter, We donít have any back panel kit for the Deluxe 4U. You will have to buy the kit directly from the DIYAudio Store. Kind regards

For My BA-2 front end, I am struggling a bit with the resistor /capacitor brands and values:
4 10K R201, R202
4 47,5K R203, R204
2 1K R205
2 221R R206
2 100R R207
4 750R, 3wR208, R209
4 47,5R R210, R211
2 150R R215
2 5K P201
4 20pF C201, C202
2 10uF, 35v C203
4 1000uF, 35vC205, C206, C208

I would appreciate if anyone could point me to a good brand.
Would Audio Note 0.5 watt resistors be overkill?
Would a 47K resistor be alright to use in place of the 47,5 k one specified for R203 and R204?

Does anyone have a photo of a fully stuffed BA-2 board?

Otherwise I have almost all the "big" parts in the house. I still need to buy the last components to stuff the BA-2 board, buy internal wires, M3 screws, nut, washers, spacers and so on.

Thanks,
Peter

Default Resistors

You want Vishay/Dale RN60D where it's specified 1/4 watt resistor. The part number for your 10k ohm resistor would be RN60D1002FB14. They're available at Mouser.

For R208 and 209 3w resistors you want Panasonic part number ERG-3SJ751. Also available at Mouser.

For the 1000 uf 25v this would work - ECA-1EM102.

I'm using ClarityCap PX for the output caps in my BA-3FE but you have a plethora of choices ranging greatly in price. You can find a selection of caps at Madisound. The ClarityCap PX 10uf is here:

I'm not sure about the 20pf and 1n film caps.
