Bigbottle MM/MC Hybrid Valve Phonostage PCB

[Bigman80]

It's arrived. Quality board mate.

Ah! Awesome.

Thank you.

Oh, before I forget,

The BOM calls for Green LEDS bit apparently that's a mistake.

Should be Yellow or Red.

I'll update the BOM to reflect this.

Is this red LED the right one?

That will do the job. Virtually any red or yellow led will be suitable, 3mm or 5mm.

Hi Bigman80,

I will sign up for a PCB when you start another GB.

Thanks.

No worries,

Lets start a list, copy and add yourselves with number of PCBs required.

1: scobham - 1

Booo, looks like I waited too long to pull the trigger on the BOM from Mouser and now the BF861C,215 is out of stock: BF861C,215 NXP Semiconductors | Mouser. I think Digikey still has some, so may make a separate order, but first wanted to check if there are any equivalent alternatives.

For those interested, this is the BOM I'm working on, but no guarantees on its accuracy! Mouser Electronics

Thanks!
Greg

@Bigman80, what is the price for the board - I might get 2, instead of one Also, if anyone can tell ballpark total price for the build?

Hi,

Depending on where you live, its between £30-37.50 inc delivery

I build one recently for under £400. That was with valves and the chassis included

I have some matched BF862's spare if anyone needs for this build.

How closely matched? I may take a couple for me lol

Hi, I have not got many left but:

Price each BF862 0.35 GBP or
Price for a 1% matched pair BF862 1.50 GBP

P&P 0.88 GBP in the UK. Anywhere else you need to let me know so I can work out the postage.

Im trying to find some LSK170C or 2SK170C, so if they don't materialise, i may be in touch.

Not to be dense, but I have some matched 2SK170BL pairs from a previous project. Would that work fine for the through hole pads for Q2L/R?

Thanks,
