Do You want to substitute an SMPS with a linear supply ?
Voltage before rectification is usually 1.4x lower.
26V bridged rectified & filtered requires a 18.5V transformer.
You also have to determine the current needed by the Wattage powered & give a bit of margin. For a 100W amp add 50% so a 150W or even a 200W trafo if You play loud.

One more question . . .
The transformer was removed from a Bose Companion 5. Bose claim a power consumption of 300w. Using this information what is the likely VA rating of the transformer?

Does it mention anything on the casing? Most countries have to have the V and I on the case and 9/10 that's RMS.
Just be careful of power related to musical output.. like peak music power, or peak power at a particular frequency.. as it wouldn't mean a great deal to a transformer with a different amp from what I could see.
There will be a slight difference in voltage without load and with load too so simply measuring it across the terminals isn't likely to give you the right figures.
