Hi Rutilus.

One preamp board has two channels. So I guess you mean you need one board. Please confirm.

Please also share your email address for sending the paypal invoice.

Thank you
shaan

@rutilus
I understand you cannot private message @shaan because you are a new member, but you can ask shaan to start the message.

Let me know if you want your private information removed from the public forum.

The new private message conversations look just like a forum thread so I also didn't care to look where I actually came when clicking on the emailed link and replied to the comment.

@shaan

Looking forward to building this preamp:

By using a higher gain than the default +6dB, it can be made to put out 10VPP into 600ohm headphones or upto 25VPP to power-follower type amplifiers.

So let's pretend we are using an F4 amplifier (current gain only). How much gain can we comfortably raise this preamp to assuming we use the highest voltage rails (+/- 15V) with the least amount of distortion (i.e. SIG at minimum)? Let's assume we are driving it into an impedance of 47k ohms (the input impedance of Pass F4).

Thanks,
Anand.

Any more boards, cost?

Shaan, hello.
Until now i use the peeceebee pre with pass f5 and v4h.
Like poseidonvoice above, i want to use with pass f4.
Please advise the changes!!!

 

[Oracle1]

I know that increasing R55~R58 give more gain. (#362). Let say 2,7k or 3K is enough for F4 ?
I have from you second pre pcb to solder...
i am waiting for the V5...
lot to do!!

 

[marconi118]

isn't this preamp similar to weyn line stage 2018?
