pulled a disassembled 8487A from the scrap bin, the cartridge turned out to be blown and the bellows

and that someone can point that out to me. I've been all over this forum and every scrap of ST documentation

on the A2 board is defective, could I just scrap a board from another HP/Agilent/Keysight 6632B and replace it in my power supply? Thanks for help, Markus

我有一个带有OPT 1EA高功率（SN3537A01391）的8648C，它的A10频率很差。分机。 Asy（08648-60040）看来输出放大器IC（金盖子用4个艾伦帽螺丝固定到位）。有没有人知道这部分是否可用，或者是否有人将一个拥有该模块的单元分开。还可以在此发生器中使用其他A10模块（可能是没有1EA功能的模块）吗？有人修理或更换这些吗？这是我的火腿小屋所以我的预算有限（我这样做了）。因此，如果有人有任何建议，他们将不胜感激。 Sam W3OHM 以上来自于谷歌翻译 以下为原文I have a 8648C with OPT 1EA High Power (SN3537A01391) that has a bad A10 Freq. Ext. Asy (08648-60040) it appears that the output amplifier IC (the one with the gold lid that is held in place with 4 allen cap screws). Does anyone know if this part is available or is anyone parting out a unit that would have this module. Also is it possible to use other A10 modules (perhaps one that does not have the 1EA feature) in this generator? Does anyone repair or exchange these anymore? This is from my ham shack so I have a limited budget to repair (I got it this way). So if anyone has any suggestions they would be greatly appreciated. Sam W3OHM

大家好，我刚才买了一块斯巴达3an板。不小心，我插了一个错误的电源适配器，而不是斯巴达套件的适配器。现在，即使连接正确的适配器，电源LED也会闪烁。我注意到调节器电路坏了。我是否有可能再制作一个额外的调节板来为斯巴达提供动力？谢谢。以上来自于谷歌翻译以下为原文Hi all, I have purchased a spartan 3an board a while ago. Accidentally, I have plug a wrong power adapter which is 12V instead of spartan's kit's adapter. Now, the power LED is blinking even when I connect the right adapter. I've notice that the regulator circuit has broke. Is it any possibilities that I make an additional regulator board to power the spartan again? Thanks.

背景：MPLAB X IDE V4.15，XC32 V2.05，和声V2.05，PIC32 MX430F064 H，PIC32 MX130F064 D。本周末我打算进行一些挖掘，但无法绕过它。我看到的是，上面的130F的Bootloader项目只使用7100字节的总程序内存，而430F使用10916字节。这种差异，至少在地图文件中看起来，来自一个标记为异常内存使用的区域。这个区域使用3652字节的内存。我的问题是我能通过一些设置和谐地关闭这个吗？我不执行/重写任何异常处理程序，而130F的引导加载程序在没有这一部分的情况下看起来是完美的。此外，两个项目在应用程序配置-Gt；异常处理和高级异常和错误处理下都具有相同的设置。 以上来自于百度翻译 以下为原文 Background: MPLAB X IDE v4.15, XC32 v2.05, Harmony v2.05, PIC32MX430F064H, PIC32MX130F064D. I meant to do some digging this weekend, but couldn't get around to it. What I'm seeing is that my bootloader project for the 130F above only uses 7100 bytes of total program memory, whereas the 430F uses 10,916 bytes. The discrepancy, at least looking in the map file, appears to come from an area labeled Exception-Memory Usage. That area uses 3,652 bytes of memory. My question is can I turn this off through some setting in Harmony? I don't implement/override any exception handlers and the bootloader for the 130F seems perfectly fine without this section. Additionally, both projects have the same settings under Application Configuration -> Exception Handling and Advanced Exception and Error Handling.
