Vintage 1960s Dynaco Stereo 35 ST35 EL84/6BQ5 amplifier :
Pretty much fully electrically restored: New PC13 circuit boards from Dynakit + new multi-cap power supply capacitor (see label in photo - I kept label off for vintage look but it's a brand new capacitor w/ the correct factory values and you can apply the adhesive label to metal "can" if wanted) + new gold plated RCA input jacks + new power supply dropping resistors underneath + new polarized power cord + new power supply rectifier diodes + added a thermistor to soften tube start-up current and drop line voltage just a bit given today's home voltages are a tad higher than in the 1960s.
Only non-stock/non vintage mod was I added a power switch on the back - since these amps otherwise have to be turned on/off plugged in to some sort of pre-amp.
TWO SETS OF VINTAGE TUBES INCLUDED (gives you a full working spare set !)
1) Vintage set of Qty-4 Dynaco Label 6BQ5 tubes labeled 70-09 274 which means they are almost certainly RCA and have the solid disc halos. Qty-2 Dynaco Label 7247 w/ Great Britain labels (probably Mullards). They tested and worked perfect after being in storage for several years.

2) Vintage set of Qty-4 Baldwin Green Label 6BQ5 tubes (almost certain they would be made by Sylvania given their vintage age) and Qty-2 vintage 7247 pre-stage tubes (one is labeled Great Britain and label on other is not totally readable)
Amp works perfect w/ no hum or noise or other issues (amp is silent w/ volume all the way down) and x-formers run reasonably cool to touch at temps expected for this type of tube amplifier.
Since I don't run this amp all the time - I burned it in on the bench for several hours and it's working great, all voltages check out and plays perfectly as shown w/ MP3 player input in photos.
Some very minor wear to the brown cage and bottom metal plate - common for an amp of this vintage and age. Transformers are original Dynaco as labeled.
