Slightly Complicated

Marshall George,

Mullard became attached to Philips so you will often see early-mid 70's Amperex -the "orange globe" labelled that will have Mullard, Blackburn etched codes. I have both ECC83 and ECC88s so labelled. These tubes- to me- are indistinguishable from the Dutch or German Philips tubes of the same era.

I may not be paying enough attention, but I can't spot differences in construction between those 70's Mullard made Amperexes and mid 60's Dutch Amperex Bugle Boys.

There are common manufacturer rebranding of Mullard tubes- a common example I've seen would be with mid-60's Fisher gear. The 800D receiver I have happens to have 8-smooth plate Telefunken ECC83s, but I often see sets of Fisher labelled Mullards for sale that came from these mid-60's Fishers.

My EICO HF-14 has all it's original and again they are "EICO" Mullards. I think some Dynaco PAS preamp kits came with "Dynaco-Mullards".

I'm certain others will come up with other manufacturers that relabelled Mullards. Like telefunken, Mullard was a known "premium "maker and the gear mkaers would keep "Mullard" on display as a sign of higher quality.

In answer to your question, Mullards are not strictly Mullards- depending on the era they were made. They eventually became Philips tubes that shared Philips tooling and standards. These "Mullards" to me sound identical to the contemporary Philips stuff being done on the Continent. I think there were even Mullards made in this system as far flung as the Philips factory in Australia- though I may misremember.

The inter-relationship of tube makers gets very complicated by about 1980!

Cheers,

Bambi B
