(OT): Anyone good with ARP PCBs?

From this auction

Worth a few bucks??

Cheers

1: Omni ensemble chorus FX board (missing some matched trannies though)
2: “D Mod” maybe the ring modulator module from 2600 (spot the tempco)
3: 4072 or 4075 24dB filter module (unpotted!)
4: no clue, probably nothing of value
