[TenTec] Argosy 525D filters not working

[lhilborn5]

Are  there instructions somewhere for installation of accessory filters, noise blanker etc ?I removed some crystal filters from one 525D to another, now the one with only the 217 and 220 modules remaining goes silent when I press the Xtal switch in. When I push Xtal switch out the receiver audio comes back to life.Thanks for any wisdom73 Lynn  VE3CSSSent from my Galaxy Tab® S2
