Sherwood 7200 dial pointer light - difficult to replace?

[pdxtim]

The FM and stereo indicator lights and the dial pointer light on my Sherwood 7200 are burned out. I swear these were working when I got the receiver but now they're kaput. The roundish FM bulb and the long single filament stereo indicator light appear easy to access but the replacing the dial pointer light seems more complicated. The bulbs do have current.

Is there anything out of the ordinary I need to know when replacing the pointer light? If it's a project I may just live with it being out. Also, the FM bulb I have as a replacement is smaller in circumference than the original. What can I use to fit it securely into the board opening? Thanks in advance for any help

Did you ever get it replaced and how hard was it accessing it? What bulb did you use?

edit - never mind, just found your other thread covering this.

It's been a few years but if I recall correctly I was able to get the old bulb and the wires out of the 2 holes in the plastic box enclosure without having to drill holes in the plastic box. I got the bulb from Dave Wojnarowski (dwojo) who is a great resource for vintage stereo bulbs. PM me if you need more info on Dave. Good luck!

Wow, great info. did really expect a reply on this old of a thread. I’m putting together a list to order from Dave and was researching how the pointer bulb could be accessed and replaced. Much appreciated.

It doesn't look like the 2 wires leading to the original light in the small box will come out, I thought the plastic was kind of melted around the wires, but you can get them out. I forget exactly how I did it though... maybe I cut the old wires inside the box??? After the old light is out, you of course just thread the wires from the new light through the holes, genlty pull the new bulb up into the box, and you're then ready to solder the new wires to the old ones. (Or the new wires may be long enough to reach where the old wires connect to the board, I forget). Just be sure of course to allow enough slack for the dial pointer to move all the way to the right and left of the dial.

I've received a ton of help from others on this site so it's nice to be able to pay back. Have fun!

Again, very informative. In the morning I will take a better look at it. I just got a reply from Dave and will be placing an order tomorrow.

i still need to match pairs of transistors for the two driver boards. I’m building a Wheatstone bridge type circuit to find very close pairs. Right now one channel has about 107 mV dc offset, the other around 8 mV.

I just want to get this finished. My stash of vinyl is calling me. The receiver sounds really clear and good streaming XM using tiny Altec bookshelf monitors on my workbench. Mine also has the non-working on/off with an inline switch on the power cord. Works fine, just not as convenient.

again thank you for all the info.
