Just aquired a fantastic shape vintage AMPEG SVT Blueline. Curious as to what year the experts think this amp is? Here are some other interesting features:
- GE6550 USA Power Tubes
- GE Tubes in the lower chassis as well.
- Appears like the preamp tubes are a combination of old tubes (havent taken them out yet to fully confirm)
- Two prong power
- All the weird screw heads
- an original, "hard wired" speaker cable. Aparently was only changed the end from 4 prong to 1/4"
- Unique band logo on top "Rockestra"
- Both transformers appear original, one has "Hammond" on it. saw a similar example on ebay with same part numbers
- fan updated
- original tolex, etc.
In any event, very quite at idle, with a hint of occasional microphonic ring when turned up. Sounds amazing when running full!!!! Worth it.
Also in pic is my stock 1961 Navy Flair Ampeg B15 to match for a heavenly combo.
Any input greatly appreciated!!!
