STK392-560s for Sony projection set?

[rpm1200]

Hi all,

I have a Sony KP-43HT20 projection set, vintage 2003, that I'd like to get going and give to a friend. It needs two new convergence output chips, STK392-560. When I had to replace the convergence outputs on my Panasonic I went to Acme Electronics, who stocks original Sanyo STK's. The replacements worked great and are still going strong. However, Acme does not stock the STK392-560. Both MCM and MAT have generic replacements, but I do not want to get garbage chips that will blow up within a year.

Encompass has a non-Sanyo replacement chip for a bit more. Are they a more reliable source?

Any alternate source or cross-reference for these chips? I'd like to stick with genuine Sanyo if at all possible.

Thanks!
