在8752C上有缺陷的A3源可以使用8752A部件吗？

嗨，我的8752C VNA显示有缺陷的A3光源，由频谱分析仪检查sma输出端口确认（在任何功率设置下小于-30 dBm）。
我追踪问题（s？）到铸铝射频部件，YIG和腔输出都很好。
输出前的最后一个陶瓷模块（我相信ALC探测器）会在连接一些金迹的某些黑色斑块（电阻器或电容器？）上显示一些物理损坏（烧伤/裂缝）。
其他模块使用双筒望远镜看起来很精致，这当然不是很多，除了一些希望它可能没问题！
我想更换有缺陷的陶瓷模块，从最后一个（ALC探测器？）阶段开始，然后可能是前一个（放大器？），我找到了一个可以清除A3射频陶瓷模块的8752A。
有人能告诉我8752A的A3源（或至少是陶瓷模块）是否相同/兼容，比如我能做到吗？
这里附有我的A3光源图片，RF铝盖打开。
非常感谢你的帮助！

  Hi,

My  8752C VNA shows a defective A3 source, as confirmed by Spectrum Analyzer checks on the sma output port (less than -30 dBm at any power setting). I traced the problem(s?) to the cast aluminum RF part, YIG and cavity outputs being fine.
The last ceramic module before output (I believe the ALC detector) shows some physical damage (burns/cracks) on some black patches (resistors or capacitors?) linking some gold traces. The other modules look visually fine using a binocular, which of course doesn't me much except some hope it might be OK!.

I want to replace the defective ceramic module(s), beginning with the last (ALC detector?) stage, and then possibly the one before (amplifier?) and I have found a 8752A that I could scavenge the A3 RF ceramic modules from.

Can someone tell me if 8752A have its A3 source (or at least the ceramic modules) the same/compatible, such as I can do that?
Here-enclosed a picture of my A3 source, RF aluminum cover open.

Many thanks for yr help!
