Various high quality pictures of this rare Amperex Holland 7308 Bugle Boy
“In 20 years of tube collecting and tube selling, this is the FIRST real Bugle Boy 7308 I have ever seen! It appears your tube was originally imported into Canada, as it has HOLLAND etched into the glass at the top. This was standard for all Philips/Amperex tubes that were imported or sold in Canada. It is just possible that for some reason the Bugle Boy labels were only sold in Canada? The Holland name sandblasted into the glass is only seen on Dutch Philips or Amperex tubes coming out of Canada.
I think, due to the extreme rarity of a real Holland made and date coded 7308 Bugle boy, that 99% of those you actually encounter are fakes from Richardson Electronics. Your pictures do reinforce some facts that still tell the real thing from the fake: The fake 7308 or 6922 tubes NEVER have date codes or production codes on them. Yours does, so I will concede that you have one of the very few real Bugle Boy 7308 tubes in existence.” – Brent AudioTubes.com/6dj8.htm
