Diodes, part number ???? Cross reference ? Little help

[Mark A Bradley]

Cobra 29 LTD,,D13 Part number 1SV215 Varicap Diode
D19 Part number HZ5C-2 Zener Diode
D22 Part number HZ90B1 Zener Diode
D5,D6,D24,D10,D12,D9 Part number 2-2AP261 Germanium Diode
D4, 2AP34A Germanium Diode.

Can anybody clarify the real part numbers for these Diodes, I am not familiar with these Part Numbers, I cannot find these so called ( Part Numbers ) at all. I have Zener Diodes, and they all begin with IN, from here I am stumped. Can anybody give me the real part numbers for these Diodes. THANK YOU in advance,,,Have a great weekend...

Found 1SV215 at alldatasheet.com. It's a varactor tuning diode, around 30pf at 2 Volts.

HZ5C is a 5.1 Volt zener diode. We always use a 1 Watt replacement. Didn't look up the Watt rating for the original part. 1N4733A

HZ90B1 is a 9.1 Volt 1 Watt zener. 1N4739A

The next one should be a 1N60, but what kind of radio has THAT many germanium diodes in it. Must be old. Silicon diodes pretty much took over by the mid-1970s.

Pretty sure the last one is 1N34.

Thank you so much, now I can have a plan,,,, now I know what to switch out the Diode with now,,What I put down was out of the Cobra 29 LTD. I am working on a Uniden PC68LTW, and it is like the Cobra 25 LTD inside, I wish I had a schematic on the Uniden, every thing looks like a 25 LTD,but different numbers on the parts, so I am using the 25 schematic, and working with those numbers, and just going by placement, instead of numbers. Do you possibaly have a service book or alignment for this Uniden radio? Thanks again for all of your help, great people on this forum, 73's right back, Mark,,KB9GTB

Closest you'll come to this model is the PC66.

Schematic here: http://www.cbtricks.com/radios/uniden/pc_66/graphics/uniden_pc66_sch.jpg

Uniden changed their policy on service data and stopped providing it at all. Pretty sure the 69LTW was sold after this. Don't know where you would find it without breaking into a locked file cabinet in Tokyo.
