[TenTec] Orion II A9 Board Failure...Again!

[Jim WA9YSD]

The R.L.Drake L7 amp power supply had the same issues.  The same for their other amps.  My L-7 amp was no different.

What I did was buying some computer grade caps put them in series with equalizing resistors.  I all so added the SB-200 kit that ramped the input power supply voltage slowly to prevent the shock of the in rush when first turning it on.  This totally defies the  authentic value of the equipment in its original restoration shape.  Sure worked well, and did not have the caps blowing.

It is characteristic for electrolytic caps to go cause they dry out.  Even the USA made ones.  I had to replace many in tube type radios and TVs cause the heat generated from the tubes would dry them out.
