Actually I just searched and found the Beaux Arts Trio performance. It is on one of those discount consumer CDs "Tchaikovsky At Tea Time" on the Philips label. Considering how those CDs are usually put together I do not know if it is the whole piece or just a favorite movement?
Back again for editing. Unfortunitely the Tea Time Cd is just the 2nd movement as I guessed. Look for used or an LP, or go for the DG recording.
