Trimax Monoblocks

Recommended Posts

They look like a pair that my uncle built many years ago using huge Trimax transformers which was ultimately thrown in the bin (!!!!!) before I was into this kind of stuff, unfortunately...   Oh, the shame....

Are these the broadcast monitor style mentioned above, or different?

 

 

They are the Type 54 broadcast studio monitor amps

Hi EvLoutonian - message received & replied. The main characteristic I find with these amps is the amount of power they produce. Much higher than the stated 18wpc I guess it has to do with the huge iron they posses.

Hi all, i have a set of A54 Trimax amps and restoring them but they dont match up to any of the schematics ive found all the A54 and A54A diagrams are completly different to my amps like R1 is a resister but in the parts list and diagram its a 20k pot? there is a 56uf electro and it doesnt exsist on the diagram or parts list?

Toby, It's unlikely to be too different in the main part of the amp, and quite likely to be related to a different input source, or someone's idea of 'an improvement'.

 

If you mark up the schematic, showing the differences then it should be relatively easy to work through what is happening.  Perhaps if you don't work from the component labels on the tag board, and just work from a schematic - as the tag board labels are obviously not correct.

 

Given its age, you would be well served to do a thorough restoration and to add some protection parts in, if you have done that before?

 

Ciao, Tim
