Vends Doepfer A-124 Wasp occasion

Description

Vends Doepfer A-124 Wasp.
Ouvert à l'échange contre le Doepfer A-106-5 SEM (gris) ou Doepfer A-138-s.

Pas de traces de vis, fourni avec boîte et nappe.

Je fournis aussi 5 puces de rechange. Pour ceux qui ne connaissent pas ce module, il maltraite honteusement sa puce qui peut péter (ou pas). Ça fait partie du charme. En gros quand ça sent le cramé, il faut changer la puce :)

C'est le fonctionnement normal du module, cf. la note sur le site Doepfer:
"The module is a copy of the filter used in the EDP Wasp synthesizer which "abuses" digital inverters (CD4069) as operational amplifiers. The disadvantage of this circuitry is that the inverters die now and then. The only solution would be to replace the inverters by standard operational amplifiers but then special character of the Wasp filter would be lost. It's impossible to predict if or when the CD4069 will die and of course we test each A-124 carefully before it leaves the factory. There are A-124 which work flawless since over 10 years, others become defective after weeks, months or years. Fortunately the CD4069 is a very inexpensive standard part (should be US$ 0.5 or less). The circuit is plugged into a socket and can be easily replaced by the customer if required."
