I have several Amperex ECC88/6DJ8 O-Getter tubes with Bugle Boy or Orange Globe Logo made in Heerlen Holland in 1960's.
Amperex Bugle Boy 6DJ8 tubes are slightly warmer than Orange Globe version while Orange Globe version is slightly more transparent than Bugle Boys.
Both are great sounding ECC88/6DJ8 type tubes.
Bugle Boys are made until 1966 followed by O-Getter Orange Globe Logo version 6DJ8's which were in production until 1969. These O-Getter Orange Globe version is the best sounding and earliest production of all Orange Globe Logo versions (Later production Orange Globe versions are Dimpled Disc followed by A-Frame Dimpled Disc) .
"Warm, great soundstage and ambience with full bass"
***Orange Globe Logo:
"Warm, vibrant, lively, grainless, transparent Amperex sound. Killer tube."
