Default Vintage parts to new amp

Few days ago I took a Nordmende Caruso console from kijiji. Unfortunately, the previous owner dog pee in the console and eat some wires and a piece of the board (see pictures). Is a small dog. I've try to see if the electronics can be saved, but the HV side of the transformer was in short (I've used a bulb plug), and from 8 lamps only one was lighting. All the lamps are good (most of them are Valvo and the 2xEL84 are Telefunken). I've pull out the transformers. The wood was scraped (to smelly). If someone need the turn-table I'll give-it to him (it's in good condition except the plastic mat). Pick-up only. The amplifier is in different section then the turn-table and the speakers and only the amplifier was affected. Now, since I can't use the amplifier I want to build one with the existing tubes. Can someone suggest a schematic? See pictures for the transformers.
The OT are 10K/4.5ohms. I plan to re-use the original speakers (1 full range +tweeter per channel). The list of tubes is: ECC85, ECH81, EF89, EABC80, EBC81 2xEL84 + magic eye EM84. I plan to use the EL84 as output tubes and if necessary I can get some 6DJ8 from my old Tektronix scope (is working, but I'm not using-it). I don't plan to destroy the scope, just to borrow some lamps if needed. I only plan to use the amp with the ipod/tablet headset exit (I already own an old console in very good condition). I'd prefer to use an already tried schematic, if someone can suggest one.The PSU will be SS as the original one. Thank you.

You could try the RH84. The ECC85/6AQ8 is very similar to the 12AT7/ECC81. Recycle the O/P "iron" too.
