Hello to the group. Numbers of threads running on the HP 10811. Mine is 45 Hz low. The oven is most likely ok. I did get the can open per the various other threads and the web pix. Started testing the circuits and have found that the regulator for the oscillator isn't. Its supposed to produce 5.7V and is at 5.27V thats pretty significant. The transistor looks like a shorted collector base junction. Though I do not have it out of circuit yet. Its Q4 a 2n6429. What interesting about this transistor is its beta at 1 ma is 500 min and max is 1300. Its not a darlington. Thats pretty amazing. I am looking through my xsistors to find something close. May just through a 2n3904 in for a quick test. Its beta is nothing like the 6429. But it would help to prove/disprove the point that the low V may be offsetting the oscillator I hope. Will also embed a K thermal couple to verify the oven really is in the 80-84C region. Regards Paul. WB8TSL

Hi The regulator should be fixed, and the OCXO will work better with it repaired. That said, shifting the regulated voltage from 5.7 to 5.27 volts should not shift that oscillator 45 Hz.

I can hope I will embed a k thermocouple also.

Well learned quite a bit Q4 does have an issue. Further there is a reason it has such high Beta. Its must deliver 30 ma to the oscillator and buffer. I was quite surprised by this current level. I was guessing the oscillator was a few mils and the buffer maybe 8. The 2n3904 simply does not cut it. Need to do some digging in the ole transistors. Regards Paul.

The 2N6429 crosses to an NTE123AP, in stock at Allied for $0.80. http://www.alliedelec.com/search/productdetail.aspx?SKU=70214870&mkwid=szEc5 jMBI&pcrid=23468365337&pkw=nte123ap&pmt=e&pdv=c&gclid=CKyzu9_cybgCFWYV7AodJA sAWQ Good luck.

I find it hard to believe that NTE spec the 123AP to replace a transistor with min beta of 500... This is quite entertaining: http://www.vetco.net/catalog/product_info.php?products_id=1856 Look at the parts it's supposed to replace. (Nothing against Vetco - they are a great source of NTE components and are local to me. They are just quoting what NTE claim.) Orin. On Wed, Jul 24, 2013 at 8:42 PM, J. L.

I totally agree that a 123 will not replace it. A luck would have it I have 12 X 2n3390 xsistors Beta 400-1000. These are the older TO-98s and I will try one tonight.

Robert I can't believe you found the transistor. When I pulled it out last night, its actually a MPSA18!!! I had not had time to look it up but figured it was a ebay leftover hunt. :-) At that price I may order 20 of them. Like the gain. Thanks.
