| Supratek Owners Thread Ah, I see,.. I’m pretty sure (without seeing a schematic) that cap is feeding a regulator used to increase the cathode voltage of the DHT. It has nothing to do with the filament V if this is the case. The circuit is direct/DC coupled between the 2... | |
| Supratek Owners Thread @alpha_lam The filament is run from a regulated DC circuit not B+,. regardless, there is a small electrolytic at the regulator output (5V assuming a 300b DHT) in PS box,.. if you are referring to a cap seen in the pre (not PS box) directly sol... | |
| Supratek Owners Thread @alpha_lam gotta disagree with you on the 'if you plan to own a supertek, be prepared for a very involved experience',.. you bought a used unit and have issues, you are in the minority of owners out there. If owning a Supra was 'involved' Mic... | |
| Supratek Owners Thread @gryphongryph the umbilical is made with solid core wire and thus the stiffness. There is a stateside cable company that makes aftermarket umbilical's for the suprateks,... can't exactly remember the name. Audio Revelation maybe.. In th... | |
| Supratek Owners Thread @gryphongryph you should not hear any hum from the supply or speakers, save for a touch of tube rush/hum that is normal for a DHT. That hum/rush will be a touch more than on the SN7 output. Should really only be heard with ears next to the spea... | |
| Who has switched from a PS Audio BHK Preamp to something else? hey @thiefoflight I have that adapter and it's the one I had to rewire with a jumper in order to get it to properly work with a Decware unit that runs the heaters on AC,... just be aware,.. They assume that most all modern tube gear runs DC ... | |
| Who has switched from a PS Audio BHK Preamp to something else? Ditto to Jackd's comment above on the BHK / SN7 tube rolling,. depending upon the adapter used (and who made it), the heater arraignment will not necessarily be complimentary to the circuit,.. for example I had purchased an noval>sn7 adapt... | |
| Would like help on how to rate my old preamp Contact Mick for repair. His warranty is lifelong provided the unit has not been modded (and those mods are causing the issues),.. He has a service tech in the US. You will have to cover shipping costs but that should be it. | |
| Supratek or Don Sachs - which way to go? A little late but in reply to @Soundmasteraudio,.. The 'Domes' on the Supra's have been used in the past as needed to house output transformers. Not all of the pre's Mick builds needs that 'extra' space as most of the time the transformers us... | |
| Supratek Owners Thread HighStream, that was my impression from Mick. That this new circuit really narrows that gap between components and really just makes the perceived change in components just different not necessarily better. | |
| Supratek Owners Thread Shibui,.. I would imagine that the only tube you should pull is the Rectifier which will sever the B+ voltage and reduce the risk of a short when trying to measure. If you measuring the heater voltage, all the tubes in that circuit need to s... | |
| Supratek Owners Thread Tubes,.. all the way. Only SS component currently in is the hybrid PSA-BHK Pre, soon to be replaced with the new Grange beast that Mick is looking to put back 'on-line'. Will have a DHT and 6sn7 circuit that can be flipped between along with ... | |
| Supratek Owners Thread Hey Bob, I have Mick making me a Pre as we speak (or in que at least, lol). All Cortese models are Phono integrated pre's. The price difference ($4K / $7K) is whether or not the phono is a standard CR or the more expensive LCR version and the... | |
| Shuguang 310A vs. WE310A I ended up getting a pair of the 310 equiv (10j12s) from Russia. Just arrived this past Fri. All in all only took about 8 days to get hear,.. was expecting twice that long. Anywho, for a NOS ('early60's) tested and matched pair (w/results) $80... | |
| Differences between Line Magnetic 518 and the 219 I've owned both,.. currently still have the 219,... I originally sold the 518 because I was very curious about an Ayon integrated with it's discreet vol. control. While I had the 518 I acquired a Wytech pre (Jade 2.1) and it convinced me of th... |
