Hi Group,

there's a HP 1801A dual channel vertical amplifier for 180 serios 'scopes on ebay.
the one shown has a channel 1 output on the front panel and a magnifier switch.
I have another 1801A at home that doesn't have the output and magnifier.
Is there an option to the 1801A that adds the output and magnifier?

Many thanks,
Andi
