Pumpkin preamp - ordered by Steen , official making thread

tweaks for Nicola & Generg

For Nicola Sartori :

look at schematic ..... pairing PSM LS with :Pumpkin: is easy , and we only need to increase input impedance of Pumpie , so we don't need any buffer stage in between : increase both R1 and R3 to 47K or 56K , increase both R5 and R6 to 390K , decrease C1 and C2 to 1p5-2p2

for Nicola and Generg - substitute of both Q5 and Q7 (IRF9510) with 2SJ313 : decrease both R11 and R16 to 15R , decrease both R7 and R8 to 220-250R

readjust offset ;

it's useful to put two resistors which values are in rrrrrrrrreddddd

enjoy ....... :clown:

Whatshould we do without Mighty ZenMod and his incredible presence,
...... Meanwhile I suppose the number of his heads on his shoulder must be over twenty five,
Shiva was harmless compared to him.....

Thx, thx,thx,

Hi Zen Mod, :Popworm::Popworm::Popworm:

I tweaked pumpkin with your recommendations, I had more gain in the stage, is that possible? I reduced the gain 47k instead of 100k.

the sound is different, difficult to say ...... more clarity, less dark, very precise, less warm, more attack.:cheerful:

I have to hear more material, of cause I was used to the old pumpkin sound that was a bit more relaxed.....

very interesting......

the pleasure continues, tweaking frontstage of BA-1......

have a sunny day🙂🙂🙂🙂🙂: and don´t forget :drink::drink:
