After nearly 33 years of faithful service the strobe light will not
light. The turntable runs fine otherwise. Assuming the light
bulb/lamp has burned out, can it be replaced? If so, where can I get a
new light (if they're still available)? My understanding is that it's
messy to replace (a lamp soldered on the PC board I believe). I guess
I can use the turntable wirthout the strobe light working (and use
strobe discs to adjust the speed) but I'd really like to have it
working. Many thanks for the help/comments.

Most turntable strobes used neon lamps. An LED would not likely have gone
bad, and it's unlikely that it used any sort of incandescent lamp.

New neon replacements that one can get these days are cheap made-in China
crap, and whereas your original lasted 30+ years, you'll be lucky if the
replacement lasts 3 years.

That's the world we live in...

I have a couple of small wire-ended neon lamps which are surplus to my
needs, and if they suit, I would be happy to mail you one with my
compliments.

They are about 10mm long, 5mm diameter with two wires coming out of the
end. They will need to be soldered to a series dropping resistor.

If you can send me an email direct with your mailing address, I can drop
one in the post.

My email address is as above, just remove the "nospamplease"

Best Regards

S.

Hmm common neon bulbs are rated for 25,000 hour life. There are 8760 hours
in a year. 3 years seems about right.

If you're playing vinyl 24 hours a day :-) How many weeks do you get
off a stylus? And have your records any groove left?

Many thanks for the reference and reminding me to check the manual! I
have this manual but I guess after 33 years I didn't remember how
detailed it is. I'm slightly embarassed about that but I still need to
find a suitable replacement light. This doesn't look too scary to
repair (I hope).

Yes. Check page 32 in the user manual (page 28 in the pdf below).

I think the subject of this message should be changed to "Need strobe
lens for Thorens TD 125 Mk II turntable". I just took the turntables
off to examine the light and discovered that the strobe lens is broken.
Since the light is held by pressure to its contacts by the lens and
since the lens is broken, the light will not work. I'm going to try to
glue the lens back together (with expoxy glue?) but if that doesn't
work is there a lens out there that I can get? The light, it turns
out, still works fine. Many thanks again. PS: I would still like to
get a light to have on hand just in case I really do need it some time.

**I've done dozens of these things. Forget about trying to obtain a
replacement neon, they're hard to find, or very expensive. Fortunately,
there are other options. Tap into the low Voltage AC supply and use it to
run one or more LEDs. Most of my clients prefer blue nowadays, as that is
the colour de jour. Side benefit is that the LED/s last pretty much forever
and, if you choose the right LED, can be significantly brighter.

I wasn't talking about 3 years continuous use. The actual hours accumulated
in my mind would have been MUCH lass than that.

Changing the subject a bit, I've been seeing MCM fuse lamps and bayonet /
screw base lamps failing after less than 20 hours usage. Made in Taiwan /
China. It's unfortunate that where the originals last the user 30+ year,
when these lamps are replaced in the course of a repair, the lamps go out
within a month or 2 of average use.

I've gone to LED replacements for these lamps, from a guy over on eBay.
They're about 4.25 each, but you only have to do the job once.

What a wonderful manual! A tribute to Thorens.

This seems to be a widely-used approach that simply works.
