Bigbottle MM/MC Hybrid Valve Phonostage PCB

[Bigman80]

Hi,
Does anyone have any spare BF862 or BF861C fets they like to sell?
Please send me a PM.
Thanks.

I have a few 861C. How many do you need?

+1 PCB for next GB, i am interested too.

GB ? Yes?

Don´t build this MM/MC amp you will be dissapointed...
Just joking!I sold my Paradise preamp when I listened to this one.
That tells you everything.... 🙂

Where can I get one pcb? Is there a GB ?

Transformer voltage

Hi all, although the transformer I bought is specified for 0-165V and 0-9V (no center tap), it measures are 0-195V and 0-11V.
My question is: how high can it be. I know that it is regulated on the board but I dont want to fry anything.
Thanks
Julien

That 195V is very high and will give less than optimum performance of the circuit.

You NEED a centre tap for the heater winding, it will not work without.
I would suggest a new transformer specified to the correct voltages. if you have high mains voltage specify the primary for that voltage.

Nope.
Someone tried to fake PCB, so Andy and Oliver decided to stop GBs.

Thanks for that. I had a plan for the missing center tap but got surprised by the high voltage as it was sold as 165V. I’ll get a custom transformer from audiophonics.

Hello everyone,

I have been reading a lot about this project and it caught my interest (a bit late to the party, I know). Are there perhaps any populated (or unpopulated) pcbs left?

All the best,
Alwin

 

[Ryssen]

Whats the differens betweene the old and the new one?

Please ignore the above post... 🙂

At one point I believe it was possible to buy a built and tested board, not sure if that's still the case. As for a MKII, I see from the Facebook page there's something called BBu (Ultime) Phonostage. Dual mono, that's a lot of valves. This thread at audio addicts too.

Can only dream it's on offer as boards...

Hi @Bigman80, would you still have a couple of BF861C to sell? I, unfortunately, damaged one, and I can find them anymore. I tried replacing them with another model but I get a lot of noise. Thank you to let me know.

Hi Julien, I've got some BF861B parts you can have.

You can still buy a fully built and tested BB3 PCB, just drop me a PM.

The BBu will not be available in the DIY sector.

Unuccessfully tried to find the pcb at diyaudio store.
I'm interested.
How can I order?
Regards from switzerland

Send Bigman80 a PM.
The fully built and tested PCB is available from him direct, if he has any.
