For some reason this build gave me some problems figuring everything out what went where and so on . The Sp14 went much easier for me . Probably because there were less instructions that went with this kit , I guess it was ment for people with more experience than me. Newbee mistakes mostly , luckily nothing major.
Roy jinxed me by saying if I could do the SP14 the PH15 would be easy . Even with no attenuators and the less wiring it went harder for me for some odd reason . But it turned out nice in the end , I think .
I went with the Sonicap and Caddock resistor upgrades . And added a few other upgraded resistors I could get also . You get quality parts and board all around with this kit . I also went with the larger 16" wide chassis in black for more seporation of the now two boards . And also the option of external switching of MM and MC cartridges and low and high gain switches . Since I will be probobly sooner or later be upgradeing my cartridge . And also 2 outlets since I hope to plug it into my computers sound card too and copy some of my vinyl to my computer , Like on my other system .
First I decided to seperate the power supply section from the signal section of the board , like Roy's PH14 , to hopefully lessen any chance of noise transfer , I don't know if this helped or if it was just the design of the unit but its dead quiet . My band saw made quick work of it though .
Here is the finished power supply board . Left as it came no upgrades here . With 1950's NOS RCA 12x4 rectifier
The signal side .
Two NOS Ediswan CV2492's and one Mullard CV4003 that were recomended to me here . I also bought some NOS Siemens tubes to try out later also . Two and one .
Figuring out the layout .
First fire up with tubes in it , And luckily everything went A OK with no blown fuses again .
Now all I have to do is make room in the cabinet ! I built it to fit the old components perfectly not thinking I would ever upgrade them , now I have to do some creative juggling to make the new all fit .
I haven't listened to it much yet only a few albums but like I said before It is dead quiet . I was really happily suprised . It is much quieter than my S.S. PS Audio unit in my other system . Which I've never been fond of , maybe I'll sell it and build another one of these .
So far it Sounds really nice , but it does seem a little "bright" sounding . But I think that is just the 20 year old Shure cartridge and A/M stylus there. It sounded like that with the old preamp/phono section.
But its still brand new and hasen't been broken in yet . Cartridge upgrade coming when I get some money .
When I first plugged it in to the SP14 and turned it all on there was a loud humm coming from the speakers that had me thinking OH no. But I accidently pulled the out put rca's half wayout of the preamp in the process of plugging the PH15 in . But luckily re-plugging everything in fully fixed that ! Now I guess its time to listen and enjoy my vinyl again.
