Other radios based on the same chassis:
AC/DC 5-valve broadcast band mantle set.
The 5M9 uses the same circuitry as the Pye PZ100, although they look nothing alike.
A comment on the service info suggests that this was a 'very piss poor' set. Certainly it should be treated with great care given that its a live chassis radio - if you don't know what you're doing then cut the power cord off and treat this set as an ornament only.
The following photo shows a Clipper version of the Pye PZ100 - has anyone got one of these?
Valves (5): UCH42, UF41, UBC41, UL41, UY41
Intermediate Frequency: 470kc/s
Frequency Bands: 1

General Construction Notes for Akrad Radio Corporation Ltd:
Akrad sets often consist of 3 (or 4) numbers (eg: 518, 1059) or number-letter-number (5M4), and a common pattern exists for these sets: The first digit(or 2 digits in the case of 10-or-more valves) is the number of valves, the second is the number of bands and the third is the last digit of the year. Where the middle digit is a letter rather than a number it generally refers to the type of set - M for mantle, P for portable, G from radiogram etc
Often sets can be dated by the speaker, as many Akrad sets from the Pye era have the date of manufacture stamped on the back of the magnet housing.
