[TenTec] TenTec Digest, Vol 169, Issue 10

[Robert Brown]

Al:

Thanks; I may have located a PS.  I think the audio filter is going to be the hard one to track down here.

Would also be interested in hearing from anyone who has managed to replace the PTO with a DDS.

Am curious if anyone might have (at reasonable prices) the 224 audio filter, a 220 8 pole filter and either the appropriate Airpax breaker or a decent shape Model 225 power supply they'd be willing to sell or trade?  The eight pole filter is probably the least of my wants / needs.
