I've got late 60s B15N that I borrowed and guy has broken two d-shaft pot endings. Tried to glue them, but no success. I looked at fliptops.net and they do not have replacements. Is there any place I can buy them?

69 Ampeg B15-N potentiometer - where can I find it?

You might have to buy pots with the appropriate values and a solid shaft and file that shaft to fit your knobs.
Quite Possibly, Beans on Toast May Have A Good Idea, You might also contact Mark Gandenburg at Vintage-Blue. It's pretty rare for Fliptop's not to have
a B-15N part. Did you try emailing them. I found this on the Fliptops site.

Yes but both I found are not exact replacements. It has different connections (flipped) and asd they say - they are for new SVT-CL/AVs not 70s Ampegs. That one above posted by Ric Vice is close, but has metal D-shaft ending (should be plastic) and its linear. I'm searching for Treble/Bass 1 MEG audio taper/log pot.
Finding an exact match is not always easy. Startby googling the part number stamped onto the metal case.
Electrically, the shaft being metal or plastic doesn’t matter. I sometime have to buy ¼” round metal shaft pots and carefully file them down to a D shape. It isn’t easy if it’s a steel shaft.
You want to pay attention to the power and voltage rating. You want a pot that’s suitable for an amp, not an instrument. Amp pots are typically rated for 250V and up, 1/4W and up.
As for sources, mouser, digikey, newark (farnell) are available locally in many countries. Go to the web site and select your country. Or google electronic part supplier locally for other suppliers.
When searching, you can select PCB or solder terminals. With the latter, you can run wires to the board.

They Fliptops lists two 1 meg log pots with a D-shaft
This one has a plastic D-shaft but is spec'ed for modern SVTs. The notes say it can be used on vintage amps but it must be inverted . 1 Meg Log Taper D-shaft Pot, Short Tine Oem# 70-105-12 - Product Details
This one has a metal D-shaft. The notes say best replacement for 70s era; just extend the leads. 1 Meg Log D-shaft Potettiometer - Product Details
It looks like the’re offering an acceptable solution. The pots on a ‘69 B-15 were PCB mount but the pins on the pot have to align with the board. The second pot can be adapted with wired. If fliptops says it will fit, you can have confidence in their recommendation.
