Untested but working when last powered up years ago. Helping out a former RCA
employee from whom I have bought excellent gear from in the past. Waiting on pics.
Thread will update with more items soon and pics.
I have sold items (HS66 pair) previously to diko2.
UPDATED!!! See below
Please PM me for offers on any or all.
3. JENSEN JT-11SSP-6M AUDIO TRANSFORMER—150/600 ohm to 150/600 ohm high quality audio transformer. Response of .4 to over 200Khz! Current Jensen product
4. RCA 333863-1 (ADC 3-20485 & Westlake Eng. R55-105 )—this is a high quality 15k/7.5k ohm to 600 ohm input transformer. 30 to 15KHz at +/- 0.5db, good shielding, good input transformer I also use formaking direct box.
5. RCA 901967-501 (RCA MI-10253A) Line transformer—30 to 15KHz response +/- 0.5db with taps for 125/250/300/600 to 125/250/300/600 (see spec sheet pic)
6. MICROTRAN S126-SP—600 ohm to 600 ohm, 30 to 20,000 KHz at +/- 1 db (see spec sheet pix)
7. RCA 8469304-2 ( Kenyon S-502338 ) –very good 150/600 ohm to 600 ohm audio transformer with response of 20 to 20KHz +/- 0.5db, distortion less than 0.5% at full operating level and full bandwidth(see spec sheet pix). Real nice unit
8. RCA K8871989 –a real high quality line transformer 150/300/600 to 150/300/600 at 20 to 20KHz +/- 0.5db. Operating level range -50 to +10db (see spec sheet pix)
9. RCA 3313772 (ADC 3-18792)—15k/3.75k ohm to 600 ohm input transformer, 30 to 15KHz response at +/- 0.5db (see spec sheet pix)
10. RCA 8500785-1 (ADC A15270)—very high quality 15k/5k to 600/150 audio transformer. 20 to 20KHz response at +/- 0.5db (se spec sheet pix)
11. RCA 992133 (UTC Z-2961)—100 ohm to 600/150 ohm audio transformer, 30 to 15KHz at +/- 0.5db (see spec sheet pix)
12. RCA 333864-1 (ADC 3-20486 & Northlake Eng. R55-106)—this is a high quality line/output transformer, 100 ohm to 150/600 ohm, response 30 to 15KHz at +/- 0.5db (see spec sheet pix)
13. RCA MI-9667—this is an octal based plug in audio tranfomer. Impedance is 10K ohm to 600 ohm with taps to change to 600/600 ohm. Response is 50 to 20KHz at +/- 1db (see spec sheet pix)
HIGH QUALITY 70 VOLT SYSTEM TRANSFOMERS
14. Spectra Sonics T-70—this is a 100 watt very high quality audio transformer for use in 70 volt systems. It is capable of full power at a frequency response of 20 to 20kHz without typical low end saturation found in most 70 volt transformers. THD less than 0.2% from 30 to 20kHz. When you need a very good 70 volt system response.
15. Rane TF-170—this is a 100 watt high quality audio transformer for use in 70 and 25 volt systems. Full 50 to 15kHz response and THD of less than 0.25% at full power. Good low end response without saturation.
