Totally rebuilt in June 2022, this Dynakit/Dynaco PAS tube preamplifier is ready to go and sounds great.
New reproduction (clone) circuit boards, original Dynaco PAS circuit. Ceramic tube sockets.
Carbon film, carbon composition and a few metal film resistors, every resistor is new.
All new film capacitors by CDE (940 series), ICEL (Nichicon), Mallory, KEMET, Panasonic and Vishay
(4) G.E. (USA) (Kinsman labels) 12AX7 tubes that are closely matched, balanced and test nearly NOS are included.
Brand new filter (multi section) capacitor from CE Mfg. (20-20-20-20 @ 475V), new metal film resistors on this cap.
The old selenium rectifier and filament/power supply are rebuilt using Panasonic 2200uF caps and diodes. the 12X4 tube was retained also, it is a strong and balanced black plate GE brand vintage tube.
Brand new Noble volume control with loudness taps. (loudness is functional)
The stereo / mono blend switch was eliminated intentionally. A cheap balance control is installed there as a dummy, it's simply there to hold the knob to make the front of the preamp look right.
The filter switch is new and functional. The tape monitor switch is new and functional. The power switch is new and has a new "no-click" cap installed.
The balance pot, bass and treble pots are original pieces and were each tested, cleaned, treated with Deoxit and work great. New capacitors were installed at the tone controls. Bypass caps added on the bass controls.
The selector switch is original. It was fully cleaned and totally rewired with 22 AWG stranded wire. The entire preamp was also rewired with 22AWG stranded wire.
A new Dynakit input/output panel with gold jacks was installed.
The PA-211 transformer is original to the unit, it tested perfectly, this is a cloth lead early version transformer.
The chassis is in very good condition considering age. The back was rather dirty and was cleaned but did not clean up as much as I had hoped. The cover is in all original condition and has typical scratches and marks but is straight and fits properly. New feet were installed. A new power cord was installed. All of the accessory AC sockets were banged up so I simply eliminated them and blocked off the openings.
The faceplate is original and in fantastic condition, including all lettering (rare).
I installed all new aftermarket aluminum knobs to make it look better. The original knobs were in poor shape and two were missing when I bought it. The bulb and fixture are original and work fine.
This PAS sounds just amazing. I've used it with the Dynaco ST-70, ST-35 and MKIII monoblocks and it's just excellent. A proper working PAS is just hard to beat.
I've got about 50 hours listening time on this preamp since completion and it's solid. You'll love it.
Unit is rebuilt and uses many of its original parts and is therefore not covered by warranty.
