Source for 'close enough' early knobs?

[AdmiralB]

I scored a '67 200S with funky old Hi-Fi knobs - any source for something close to the original arrow-only knobs?

I've never seen arrow-only knobs on Sunn amps. Not on my 200S, not on my Sentura II, neither of my Sceptres, not even on my PA head.

Look at the old catalogs...the early models had the numbers on the faceplate, and the knobs had arrows.

The exact knob is made by Rogan Corp of Northbrook Illinois. The part number is 155-7. Not a stock item, you'll have to order 1000. The knob with numbers is 155-29 but the font is different than that used in the 60's. They look like the knobs used on MusicMan amps in the 80's. Most people  use Fender knobs if they want numbers. Fender knobs are numbered 1-10, Sunn knobs are numbered 0-10.

Thank you!

Got the numbered version covered.

Yes, I've read about that. I've just never seen it. Does your model have the numbers painted on the faceplate?

[AdmiralB]

Yup.  Chassis is dated 12/8/67, so they were using numbered faceplates at least as late as that.

I just acquires a '67 200s head that has the numbers on the faceplate. The  knobs are just like Fender black skirted knobs with the chromy insert in the center. But no numbers, just an arrow pointer.

Did anyone ever find these types of knobs anywhere?
I did look up the Rogan Corp but really don't need 500 or 1000 of these

[Greg_M]

Oh yah
If you try to clean these knobs with 409 etc. the white will come off the pointer. The pointer will still be there, it just won't be white.

Here's a pic of the front panel of a 67 200S. No date on the amp but 67 date codes on the pots and caps. Sunn branded choke.

Mine has a very faded felt pen marking by the output transformer. You have to look at it just right to see it. It says 12/somethin/67

It looks like your chromy part in the center of the knob is starting to rust too
