Transformers for Dynaco Amps
For the Dyanco ST-70 amp, Lundahl model LL1682PP OPT is a prefect replacemernt to the OEM or other manufacturers. At a cost of $150.00 per piece, plus shipping, it is a very affordable upgrade. To complete the install, use the Lundahl 1638 transformer housing for the LL1682PP.
We do also recommend that you strongly consider upgrading the driver pcb, our Dyna-70 or Dyna-70AB upgrade kits, coupled with the LL1682PP, will make your ST-70 sing like it has never done before!
