He's got a couple pairs listed, one 1969, one 1970, IIRC. He's a very trustworthy seller, and finally cut his shipping prices in half.
I'm keeping my eyes open for some mid- to early '60s Heerlen E188CCs, but these would be tempting if I hadn't just bought those pinched waist E88CCs.
Gotta let us know how those PW's turn out bro. Hope they're a special pair.
As to the 188CC Heerlens, I've probably bought 8 or so pair looking for the Heerlen HG...and honestly I haven't found much
difference strictly based on early/mid 60's vs late 60's to very early 70's. Had some exceptional pairs in both categories. They're
like snowflakes...all at least slightly different, although all have that glorious Heerlen midrange. The dates have not been a guarantee in my case. For what it's worth...
Thanks for the input re: the E188CCs. I was thinking you, or someone, has said something similar. Snowflakes indeed
I'm pretty sure the P-Ws will be here tomorrow. Not sure I'll have time to roll them and focus. I need some "quiet" time where distractions can be kept to a minimum. As I'm sure these are used, I doubt they need much burn-in. But if anything can tear me away from my new toy (Emotiva Fusion Flex, with Lyr as preamp) to focus on just the Lyr, it'll be these tubes
