POwer and IC1

Hello, i have 2 questions
The first : I have a DC supply like 9V - 600mA - with center pin positive. 600mA is ok ?
If i have understand, I must use C1 on motherboard ? if 600mA is good

The second : For IC1 (LT1054) on filter board, I still have two TL072CP. Or in the partlist, I should have only one TL072CP.
And i don’t have a LT1054
TL072 is good for IC1 ?

(sorry for my little English)

LT1054 and TL072 do totally different things. So you need an LT1054 in IC1.

TL072 should not be used instead of LT1054!

Thx, i have understand, i must by a LT 1054.
And for AC supply part, can you help me ?

*buy

Did you buy an official kit? If so I would contact Olivier about it.

LT1054 are available in lots of places, it needs to be in DIP form though.

Yes, its an official kit, and i have juste orderring a pole mission, He could take the opportunity to send me a LT1054.

I have sent a message to olivier.

Can i speak french with you dir Oliver in this part.

I have ordering a Pole mission, Maybe you could take the opportunity to send me a LT1054 ?

Yes, if there is an electronics store not far from home

It’s a kit preparation mistake. It happens - rarely. I’ll ship a new LT1054. The customer who got 2 LT1054 and 0 TL072P is your soulmate :smiley:

  • and For the (DC) supply

Thx

9V - 600mA, center pin positive is OK

:wink:
Thx
You send that with the pole mission ?

ok for the DC supply
And one more question ! I must used C1(optionnal) or not ?

Eaty one on soundkonfusion tell me it’s better to use C1 ?
Can you explain me ?

If you have C1, solder it :slight_smile: I’ll send the missing IC with your new order.

Thx a lot for your help.
sincerely
