Since I have a dozen NE334S01, I can repair a few ARR 144 & 432 preamps for others.
So here's the deal. You ship to me in a small flat-rate Priority Mail box (cost you $5.20) and include $30 for repair plus return shipping. You can either send a money order or use PayPal for quickest turnaround (a check will have to clear the bank before shipping back). NO VISA/Mastercard/other credit cards (sorry).
Typically, priority mail takes 3-5 days to reach me. I will make the repair within 48-hours of receipt. So turnaround could be as little as 8-days or as much as 12 days (not including Sunday or Postal Holidays).
I can verify operation (gain) but not able to measure noise figure or sensitivity. I can only warrantee workmanship that the preamp is functional for 30-days. No warrantee for transmitting into the preamp or reversing dc voltage connections or dropping off your tower. I will not accept preamps that have been previously repaired by other than the manufacturer. Replacement of other components beside the Fet are at cost+15% (e.g. bad voltage regulator, broken feedthru, etc.). Not responsible for loss in shipment so include insurance if you desire that. If preamp is unrepairable, only cost $5.20 shipping back to you (balance will be refunded).
This offer is good until I run out of current stock of NE334S01 devices. PLEASE CONTACT ME via e-mail before SHIPPING!
For comparison, ARR will charge $22.50 plus shipping UPS. I can not do Factory Warranty work; contact ARR for that.
If anyone objects my sending out this e-mail - then don't read it (LOL). This is not a commercial business - a ham helping other hams!
