앰방 축(spindle)의 주유는 ROB (Caltex/Texaco Regal Oil B)오일을 아랫쪽 슬리브부싱까지 체운후 (1/3 높이), 축을 삽입했을때 마지막 5 mm 정도는 아~주  천천히

스스로 내려가야만 합니다  <- 강제로 눌러서는 안됨니다.  ROB가 없을경우 대체품으로 고급엔진오일(SAE20)을 사용합니다.

 

정확한 회전을 위해서는 오리지날 TD124 벨트 사용을 추천합니다. 두께와 칫수가 유사한 대체품으로는 정확한 회전수를 얻기가 어렵습니다. 

고무 아이들러 휠 과 벨트 청소는 메틸알콜로 깨끗히 닦아주고, 벨트는 필요시 뒤집어서도 사용합니다 .

 

SPU 침압은 추천무게의 중간값(4g)이 좋고,  Antiskating Bias는 침압의 1/2 정도가 좋습니다.  메뉴알에는 침압과 같은 값을 걸어주라고 했지만 그렇게 오랫동안 사용하면 바늘이 좌측으로 돌아갑니다... 

 

 

  Peerless K241D는  피어리스 4629 (4665) 과는 형님/동생뻘 같습니다. 그러나 가격은 3배나 비싸니... 소리도 과연 3배차이 날까요?  글쎄요....

Peerless Altec 4665 input transformer is Altec’s similar but different junior sized version of the K241D..    For those who wish to know a little more about the Peerless Altec K241D & 4665... When ALTEC was spun off from the Western Electric Co. they arrived with the product designs of the Electronic Research Products Division of WECO, including the expertise to design and build very excellent audio transformers which were marketed as Peerless Transformers from the Peerless Electrical Products Division of Altec Lansing. As Peerless Division manager Ercel Harrison once said: “Never use transformers because they degrade the signal... However, when you have no other choice, get the best damn transformer you can find.” Peerless Transformers fulfilled that need for many years to follow. In the 1950’s, Peerless designed the legendary K241D to provide balanced line level inputs for balanced tube amplifiers such as the Altec 260A. Peerless also designed a similar but slightly different 4665 to provide balanced line level inputs for unbalanced tube amplifiers such as the Altec 128A. The 4665 was also used in the reverse direction to provide a balanced low impedance output from the Altec 165A/21BR Tube Type Condenser Microphone System. The specification sheet for the 4665 claims “90 dB of magnetic shielding” and a “frequency response ± 1 dB from 10 to 25,000 cps” at a maximum level of “0 dB (6 mW Ref)” Ideal for feeding an unbalanced tube input. By contrast, the K241D is capable of handling a maximum level of “+8 dBm” into a “balanced” load. Both have similar primary windings and electrostatic shields between the primary and secondary windings. These are very different transformers, but with very similar capabilities.
