This has the original front end board and original Dynaco 7199s. RFT EL34s branded Richardson Made in East Germany. I put the Silicon Diode Fix for Russian Rectifiers; this reduces both the voltage and current stress so that inexpensive 5V4/5Z4 or JJ 5AR4 rectifiers may be used. (but is still compatible with Mullard 5AR4). Checked the power electrolytic; it is right on specification; and the coupling caps. Checked on speaker and scope for Low Noise and ran Power Triangle Waves wit...h Speaker Load to check Linearity. The Chassis is very nearly pristine; maybe a couple tiny rust spots; and the chrome and lettering are good. This has the Cover; and the cover is also very nice; very few and small signs of wear. Sorry no returns except for DOA or excessive shipping damage. Experienced seller here will pack carefully and ship promptly upon payment.
