Nanao MS-2934 MS-2932 Tube compatibility

Postby PappaLazarou » March 17th, 2017, 10:20 pm

Hi All,

I've got a Nanao MS-2934 with a Toshiba A68KSM696X tube. The mainboard appears fried - . I'm waiting on delivery of a MS-2932 main-board and neck-board I bought online (impulse purchase) and now I'm wondering if it's compatible - anyone know? Are the Dx/Dy specs the same?

Cheers,
Mike.

tubes should be identical-if not identical then fully compatible

Cheers Grant, I know they're both 31kHz chassis but I wasn't sure if the slightly different toshiba tube p/n made a difference. Will give it a try when chassis arrives.
Thanks, Mike.

They're not identical-- 2932 is fully curved (A68KJU696X), 2934 is semi-flat (A68KSM696X), but they are compatible as far as I know.

Ah that explains the part different Toshiba tube numbers.
Sounds like I'll be good pairing the MS-2932 to my semi-flat tube then :D
Cheers guys,
Mike.

Got the MS-2932 chassis and paired it up to MS-2934S Tube and it works.
Picture is a bit wobbly and degaus coil not being energized but relay clicking so possibly PTC(?)
The chassis looks like its been stored near a beach the amount of corrosion on the jumper wires! Going to give it a good clean on the weekend and recap it.
Otherwise happy days :-)
