Bride of Zen problem

Thank you for the answer.
I have 93 v without load and about the same with the load, I think I loose about 0.5 v with the load.
Maybe this is cause by a high power transformer....120VA ???

Yes, the higher the VA-rating of the transformer the better the regulation with smallish loads.

Hello ! I just want to say that my noise problem with my bride of zen is now gone. Today, I receive the new Plitron transformer and they put a magnetic shield around the transfo. Now, I have no noise at all even at very high level !!!

My Zen V4 was off during more that 2 mounth.
Thank you to everybody who helped me.

Bride Of Zen Problem

Can anyone tell me what is the physical size of the Bride of Zen Preamp PCB downloaded from the Pass site??.When I print it out it looks small for the components to be fitted..Please can someone give me the size..Please if you can email it to me .. jackyjack21@yahoo.com

Thanks..

hello.
printed out mine was around 12 cm x 13 cm...............and i built it this size.
but you can zoom it a little bit so it better fits to your parts (lead distances).
greetings

Output impedance is less then 1k? In manual is 1.5k but i think it is not correct when load is 1k and 5k pot

 

[mjf]

drain res = 1k (R104)
pot = 5k (linear)
if the pot is fully turned up: 1k parallel 5k = 830 ohm;

if the (linear) pot is half turned up: you get 1k + 2,5k = 3,5k in the signal path
and 2,5k parallel to the path.........this gives you in parallel near by 1,5k....
and that is the maximum output impedance.
