Need new tachs.

[FreeinTX]

Upon this years annual, we discovered that my right engine tach is no longer keeping track of the time. For the last year or so, my left tach is slow to indicate changes in rpm, and at times pulses. I've decided to change them both, but this is more complicated than I would have thought.

Can anyone provide any information as to what my TSO replacement options are? For example, which manufactures make a TSO tach for my PA-34-200T Seneca 2? Any advice, recommendations, tachs to be avoided, etc. Any help would be appreciated.

Thanks
