MKII output and power transformers

[mark2boogie]

Hello All,

Maybe some of you have the answer to my MKIIA/B Boogie power and output transformer inquiry - or can direct me where the answer is :

1 - for a MKIIA or B, is there a difference in size or power about the transformers between the 60W version and the 60/100W version ?

2 - any of you (have infos or) tried a conversion from 60W version to 60/100W version ? With or without changing transformers ?

3 - any of you have the different references numbers of power and output transformers in 60w and 60/100W versions ?

Thanks for your help !

A+!

The major part of answer has been given to me by TiPiMods (Thanks +++ 8) , who owns a 60W MKIIB :

PWR Trafo = X61-162318 / EIA 606-115

OPT Trafo = T60-152019 / EIA 606-121

On my 60/100W MKIIA :

PWR Trafo = X100-162318 / EIA 606-924

OPT Trafo = T100-152019 / EIA 606-825

Verdict : the transformer set is different, so a conversion then would need a transformer set replacement.

Over.

A+!

1. The 100W should be a bit thicker with more laminations.
2. Putting a quad on a 60W transformer would probably net 400V or less to the plates.
It's possible, but you would lose power, volume and may overheat the transformer.
3. 60W transfomer with no load 470-480V, under stock load 448V. 100W no load 495-500V under stock load, 470-478V. If it's a 105 PT, no load 510V and 483V with load.

Thanks for this useful information +++, Boogiebabies.

Suprisingly, there's no complete topic on this subject.

A+!

I have a Mark 2c ( converted 2b) 100/60W and a Mark 2c+ 60W. The Mark C has way better clean, where the lead 2C+ wins.
But anyway the 2C+ is more mid heavy a bit through the nose sounding compared to the mark 2c and - in my opinion, for some part it has to do with the power trafo not being the 105 but 60 version...
