Also, check to be sure that none of the 6DJ8 tube pins are bent when you install them. This is also the recommended procedure for handling the small input tubes. Use a paper towel or one of the cotton gloves (supplied) instead.
Sonic frontiers sfs 50 skin#
We suggest that you do not handle the large power tubes with your bare hands or fingers as skin oils deposited on the glass surface can “leach” through the glass envelope and cause the tube to become “gassy.” In other words, your tube life may be shortened unnecessarily.
Sonic frontiers sfs 50 manual#
This brief operating manual contains important information regarding the operation and care of the amplifier, so be sure to read this manual carefully and follow these simple instructions in order to keep it looking, operating and sounding its best! Good Luck.We at Sonic Frontiers are sure that you will derive many years of listening pleasure with your new SFS-50 stereo tube amplifier. Personally, I'd call SF and ask them about their capability to service their existing products- ask for Frank Pugliano, Tech Rep. If you really want a good tube amp, the SFs are smooth, liquid, and non-fatiging, and are good amps. When I put my McCormack DNA2DX (300wpc) back in my system, I definitely preferred the McCormack and sold the Power 2- but then I listen to a lot of hard driving R&R and rhythmic music. The Power 2 has a very smooth and nice mid-range and low treble, and was very non-fatiguing, but it did not have good bass control or articulation like a good SS amp has- although bass was plenty deep. I just sent my SF Line 2 tube pre-amp to them for upgrade to the SE level, and had no trouble making the arrangements.Ībout a year ago I bought a Power 2 and listened with it for 30 days (and I think the Power 1 has a very similar sonic signature- just 1/2 the power), and you're right- these amps are pretty neutral rather than "tubey" or euphonic. They have temporarily shifted their emphasis to AV equipment. They are temporarily not producing new product- as I understand it, but could re-start if they want to. Hi Meby The SF Power 1 would not be a "foolish" purchase, and Sonic Frontiers is not totally out of the "tube business". Your opinions would be greatly appreciated if this is foolish of me to consider purchasing? In addition the company no longer makes any products, will they honor the warranty if there are problems? More importantly will they have the parts if there is a problem since they are completely out of the tube business? Will they have technicians who can fix any potential problems? Unfortunately there are no local dealers for me to audition the equipment. My concerns are that I generally do not trust reviews and have never heard this product. (3) The price is lower new than what I can pay for used ARC gear. Since I am new to tubes I consider ease of maintenance a plus. (2) I have also heard that the build quality is good and they are easier to bias as compared to the ARC gear. This is the same that is said about ARC gear and I like the way they sound. (1) I have read several reviews that say this amp is very neutral and almost solid state like. I am contemplating purchasing a Sonic Frontiers Power 1 amp, for several reasons, although I have never heard one.
