I looked in my ECG Semiconductors Master Replacement Guide and found:
BU508A = ECG2300
D1439  = ECG2302
The 2302 is the one you want. It has the "Damper" diode included whereas
the 2300 did not.
You can buy PhillipsECG parts at most TV/Radio Repair Parts Suppliers
(Not Radio Shack). Just look in the Yellow Pages under "Television
Supplies and Parts - Retail".
The local dealer can also check his book for a later update (my book is 
1985).
