Description: Dynaco ST-70 tube amplifier with upgrades! Ready to go plug and play sounds great! New Dynakit can cap 80-40-30-20 Bias circuit was removed and replaced with this nifty little bias board with bias adjustments for each tube. No need to match pairs! Also has a nice purple led as a power on indicator. New choke New gold plated input jacks with wider spacing to accomodate larger modern plugs. Original A470 output transformers and original PA060 power transformer installed. Its the later taller stacked Dynaco transformer. Driver board is original for 7199 tubes with new capacitors. Chasssis is original and pits are visible with some patina. Chrome still has shine to it. A volume control was added. Nice if you are going direct to the amp with no preamp. New power switch. New mono/stereo switch New 5 way speaker binding posts New input jacks spaced for modern cables. Diodes installed at rectifier to protect from damage. An IEC power cord jack was installed so any performance cable can be used. I will include a standard power cable with the unit. Thermistor installed to limit startup current. Electro Harmonic EL34 power tubes are installed with GE 7199 as driver tubes. All test good. And sound great! Sovtek 5AR4 rectifier tube tests excellent. DEAD quiet. NO hum. NO sizzle. NO hiss. It includes the bottom cover with new rubber feet and a cage. If you would like to see pictures of the bottom cover and the cage, please let me know. I can send them to you. They are both in nice condition and the cage is clean with the original brown paint. I am familiar with packing and shipping electronics and will make sure this arrives to you safely. May be shipped in 2 boxes. Fedex ground insured. This is a good amp and will provide you with many years of service. Many modern, high quality parts are installed for dependability.
