I need a pic, ( if possible ) of the SMD Capacitor on the TDA2003 on a Cobra 29 LTD, took it off to replace the chip, lost the cap and don't remember on which way it goes, DUH,,feel like a DUH. Also, I believe this is a 470pf or a 47pf,or 4.7pf, any one remember, I forgot,,,I think 47pf. I think the Cap goes on leg 2 and 4,,but don't remember the way..Thanks for any helpor pics you may post. Enjoy,,73's Mark KB9GTB,,,,

Thank my friend, I am thinking it is the 47uf, that is stuck around in my brain for some reason. I have a boatload of SMD's, I been rtebuilding HR2510 PLL boards, as I am stuck with 3 of them and and all 3 don't work. I need to get on them, do you know much about these? I am having problems with setting the frequency on the PLL board, I need the adjustments on all of the pots on that board, as when I bought these, I was told that they turned every one of the pots! I scoped the board, and went to maximize all of them, it seemed to help bring yup the frequency, but not making it, as I thought of replacing the crystal's also, but I cannot find those freq's, all I have is the 10.240 and 10.695 crystals, so forget that idea. I replaced a few diodes and installed the correct ones, these radios are gonna take a lot of brain work, and this is my first rodeo with a 2510, so time to get out whatever I have, and start hunting for issues, after I try tp realign these and see about any receive. Thanks again, I appreciate all you have done for me. Now to fix a 148GTL no transmit, 1 burnt diode in 49 and 50 Final and Driver dot-23 holder on back of radio, now align time, and check no transmit, first time on one of these, SSB, don't seem to bad, remember where the pots are,,lots.Take care and all is appreciated,
