Help Identifying Transformer SLT5M329

Redshift187 · 18th August 2008, 07:40 AM

I'm wondering if anyone can help me identify the power transformer in an old amp I just acquired. The amp is a Techniques SU-Z55. The transformer is labelled SLT5M329. All I can find through google is that it's a Panasonic transformer. I'm guessing by the plate on the amp that it's a 260VA. The chip in the amp is a STK2038B, which lists a max voltage of 55V and a nominal of 36V. The main filter caps are 10,000uF 56V models, black Panasonic (CE?). If possible, I would like to salvage the transformer for a gainclone.

My best guess would be that the last two digits are the voltage, 29V, which would give around 41V DC rectified. Anyone know for sure?

Upon looking at the amp some more, it seems the transformer has quad secondaries, two each at two different voltages. A switch on the back for selecting the speaker impedance selects which voltage is used by the amp.
