I had an RCA SE similar to this that used a 5Y3 but not sure it's the same one. What's the chassis number to the right of 62122: RS1xxE?
5Y3 would be original; maybe chassis RS-188. https://www.radiomuseum.org/r/rca_vp_33vp3_ch_rs_188rs18.html
I can scan the Sams or get a original to you from the Antique Wireless Museum for a small donation.

From the transformer layout, possibly RS193
RS-193 has multiple letter suffix versions. depending on what else is in the cabinet - versions A-E are covered in Sams folder 618.-12. Versions 'H' is 663-10; 'J" is folder 704-2D.

I don't have it in my hands yet. So can't provide any more chassis info at this time.

1962(?) RCA RS-193 amp, no volume
Hi all. I've been trying to sort out a gorgeous RCA record player console/cabinet unit, and I'm about out of ideas. Problem is very little volume, even cranked to the max. I've replaced about every capacitor/resistor in sight, tested and replaced tubes, new balance pot, new cartridge, cleaned...

Have the amp now. 62122: RS193F or RS183F or RS133F. Hard to tell what the 4th value is, it is smeared.
Other number below the RS # is RVA274.

Tested the PT today and it was good. Put the rectifier in and got good B+. Cleaned the pots and selector switch. Put some good tubes in it. Powered on with DBT. All OK. Powered it up directly next. One channel quieter than the other by a significant margin. Am sure some caps and maybe resistors need to be changed out. Will do more troubleshooting this week. Superbowl time now, the baby back ribs are smoking!!

What he said! ^^^
Changed out both coupling caps today and one electrolytic. Channel imbalance issue is still a problem. Suspect there is some issue in the balance, bass, treble or volume pots. Have cleaned them with Faderlube. No improvement though. Have swapped the power tubes from right to left. It is not a power tube issue, the quieter speaker doesn't follow the power tube movement. My tube tester doesn't test 6EU7 driver tubes. So can't eliminate that as an issue.
Any troubleshooting suggestions are welcome.
