I have many Matched pairs of Amperex Bugle Boy ECC88/6DJ8 tubes made in Heerlen, Holland.
Famous Amperex sound: warm and rich with 3-D soundstage and zero driness and full bass.
As you may already know, these wonderful sounding Amperex Bugle Boy 6DJ8 tubes tend to be noisy and/or test low. At least that was my impression about many of them. Great sound but noisy/low testing simply because many of the ones on sale are heavily used, and NOS tubes are rare and expensive.
However, every one of the tubes in this lot tests very strong just like NOS or close to NOS.
Noise/Microphonics test in my phono preamp also reveals almost all of these tubes are very low in noise and microphonics (a few of somewhat noisy tubes in the lot are excluded).
Also, I can easily match them by pairs since I have many pairs available in this lot.
Bugle Boy Platinum Matched pair: $60. Same matched pair tube with Hewlett-Packard/Philips Miniwatt logo: $50
