Waiting for Vintage Gear from this century
Got a pair of 901s Series V last weekend and there is a small white paper sticker applied next to the serial number. It is just 5 numbers, 18705 or 18715 on my two speakers. These are not the serial numbers. I'm thinking it might be a build date, Jan 87 on the 5th and 15th days. This fits with when the Series V was available, 1984-1987.
