ST-70 & AB, Dynaco ST-70 kit We are pleased to offer you our latest kit, our Dyna-70. This kit will replace the original Dynaco driver circuit and printed circuit board, using the excellent sounding 12AX7 and 12AU7 triode. Tubes are NOT included with the kit!
This kit will change the way your tired old Dynaco ST-70 will sound and look! Also buy autobias board AB-Q-ST70/ST120.The benefits of upgrading your Dynaco ST-70 amp with our Dyna-70AB kit are: - a modern tube circuit using a LM334 based constant current source for a stable circuit
- with the auto bias, there no more having to keep an eye on the output tube bias setting. The auto bias module will keep the pre-set bias for the life of the power tube! The bias level is pre-set by us to suit the EL34 family of tubes.
- not to mention that your ST-70 amp will look pretty cool with with blue LEDs that shine !
Should a tube fail of the auto bias module can no longer maintain the preset bias level, the relevant LED will go out indicating that the power tube needs to be replaced. It is THAT simple!
Even tubes that are not well matched, the auto bias module will maintain each tubes' bias level at the preset level! So the output stage is always well balanced and held in equal bias!
