CAS voltage not the same

[Paul Birkeland]

Take all of the jumpers and leads off the transformer you believe is bad, but leave the wires on 5 and 10, then recheck the AC voltage across 5 and 10.

 

[bqc]

with all leads and jumpers removed except at 5 and 10 on the left transformer, with input at full volume, the AC voltage across 5 and 10 on the left transformer is 55V while the AC voltage across 5 and 10 on the right transformer is 120 V

So can we conclude that there is a short inside the transformer on the secondary winding? If so what are my options? Is the transformer still under warranty ? if not how much would it cost to get a stock replacement transformer and how can I order it?

 

[Paul Birkeland]

Now lift the wire off terminal 10 on the output transformer, then measure the AC voltage between this wire and terminal 5 on the output transformer.

 

[bqc]

with wire on left transformer terminal 10 lifted, AC between wire and terminal 5 on left transformer is 140V, a jump from 55V to 140V, while the AC voltage between 5 and 10 on the right transformer remains at 120V

You can get in touch with replacementparts(at)bottlehead(dot)com regarding ordering a replacement output transformer.  It would be helpful to get that one back, just to see if there's anything we can learn from it since we have never seen one of these that wasn't working properly.

So now what?

ok thx
