Amplifire card VT 3015
Probably the most used amplifier card in the 80/90s. But - you can still find this card in many older blowing machines today. This can also be guessed from the repairs that are not slowing down.
This card is considered to be a bit complicated to adjust when you have to do it for the first time.
But practice makes perfect. The successor - the Bosch modules - have simplified things.
Rexroth released a new version of VT 3015 in the 90s. Unfortunately, it is not very different from its predecessor, but the new variant is by far not as vulnerable as the old one due to its modern design.
We are still repairing this card.
